feat(boot): Name the log and the banner after the kind of boot

EN_Cold_Warm_boot = 1 opens Logs\Blanton_Reboot_Cycle_<ts>.log and prints
a "Reboot Cycle : N" banner each round; = 2 opens
Blanton_Power_Cycle_<ts>.log and prints "Power Cycle : N". Three sites
branch on the flag now: the log name, the banner, and the boot itself.

Two things follow from it.

With EN_Cold_Warm_boot = 0 there is no longer a logopen either, so the
run that already hangs at wait "Booting in blind mode" now also leaves no
log to show where it stopped. EN_log = 1 on its own no longer produces a
log from this macro.

And anything that parses these logs has to accept both banners. The cycle
banner is the record separator the check-point and per-segment timing
reports are built on, so a parser that only greps "Reboot Cycle :" finds
zero cycles in a power-cycle log and reports nothing without complaining.

The logopen timestamp flag stays a literal 1 rather than EN_timestamp the
way Script A does it. That is the right call here - the per-segment
timing analysis is derived from those timestamps and there is no other
way to recover them - but it does mean this macro ignores
EN_timestamp = 0.

Recorded under V1.2.2 in Script A's history; the header version is
unchanged because V1.2.2 has not been tagged.

+# v1.2.0 — SerDes DSC capture, and the macro now waits on the DUT
+
+## ✨ New features
+
+**Full-machine SerDes DSC capture, before and after the soak**
+* `bcm_dsc_scan.sh` runs `phydiag <port> dsc` through the Broadcom diag shell across the whole port list — one 100G port plus the 200G ranges, about 445 per unit, on both units — and writes the raw log under `Blanton_Script/log/`, then copies it to `/host/hw-eval/jobs/`.
+* Script A takes a baseline and Script C takes a closing dump, so the pair brackets the stress run and the two are directly comparable.
+* `-u 0` scans one unit, `-f <name>` names the log (`%u` → `u0`/`u1`, `%t` → timestamp), `-F` overwrites, `-n` dry runs, `-C` skips the copy. A name without `%u` gets `_u0` / `_u1` inserted automatically, so unit 1 can never overwrite unit 0.
+* Every run ends with `### DSC_SCAN_DONE rc=<n>`. `rc=0` means every port returned a complete dump.
+* `phydiag ... dsc` is read-only — it does not change any SerDes setting.
+
+**`bcm_dsc_parse.sh` turns a raw DSC log into two CSVs**
+* `<prefix>_lane.csv` — one row per lane: TXEQ, RXFFE, DFE, EYE, SNR and the rest.
+* `<prefix>_pm.csv` — one row per `pm_id`: temperature, PLL, lane count, SNR/EYE statistics.
+* POSIX `sh` + `awk`, no Python, so it runs on the DUT as happily as on a laptop. Lane rows are read by the order of their bracket groups rather than by fixed column positions, so the SDK re-spacing its output does not break parsing; a row that does not yield 9 groups is reported as `UNPARSED` on stderr instead of being parsed wrongly.
+
+**`EN_TX_FIR` in `config.ttl` — the DSC scan is off by default**
+* A full scan is about 10 minutes and both Script A and Script C do one, so the shipped default (`0`) keeps ~20 minutes out of a routine run. Set it to `1` when the SerDes data is what you are after.
+
+**The macro now waits on the DUT instead of on itself**
+* Every `pause N` in Scripts A, B and C became `sendln "sleep N"` followed by `wait prompt_sonic_root`.
+* `pause` stopped the macro for N seconds without touching the DUT — the shell sat idle and the macro was guessing how long the previous command would take. On a loaded DUT the guess ran short and the next command went out before the previous one had finished, putting the whole run a beat ahead of the switch. Now the wait happens on the DUT and the macro resumes when the prompt actually comes back.
+* It also means the wait appears in the console log with a timestamp, so a round that ran long is visible afterwards.
+* Timings changed with it: the management-ping sample in Script A is 15 s (was 30), the settle after each traffic `clear` is 5 s (was 15). The traffic run itself stays 15 s and Script B's monitor loop stays 60 s.
+
+## 🐛 Bug fixes
+
+**The DSC scan only ever scanned one port — and reported success**
+* The scan loop read its port list on stdin, and `bcmcmd` reads stdin too, so the first call swallowed the rest of the file and the loop ended after a single port.
+* Nothing looked wrong. The log held one port marker and one dsc block, the marker-to-dump comparison passed because both numbers shrank together, the exit code was 0, and a 445-port scan simply finished in seconds.
+* The loop now reads on file descriptor 3 and `bcmcmd` is given `< /dev/null`, and there is a new check that the number of iterations matches the number of ports in the list — a check that cannot be fooled by the loop ending early.
+
+**Dead call sites removed from Scripts A, B and C**
+* The commented-out 100G PRBS calls, a duplicated commented 100G port-status block in Script A, and the stale `bmc_monitor_ddr.sh` block in Script C have been deleted. They had been dead since bring-up.
+* `port_prbs_monitor.sh` still ships and still runs by hand — but re-enabling it means writing the calls again, not un-commenting them.
+
+## 🔧 Changes
+
+* **Script C no longer prints the BMC poll log or the mlucas log to the console.** Both files are still copied to `/host/hw-eval/jobs/` and out to the USB stick with everything else; only the master log got shorter.

+
+## ⚠️ Before you run
+
+* **Replace `config.ttl` along with the macros.** `EN_TX_FIR` is new, and Tera Term aborts on an undefined variable rather than treating it as 0.
+* **`bcm_dsc_scan.sh` needs the execute bit.** Script A and Script C invoke it as `./Blanton_Script/bcm_dsc_scan.sh`. Without `chmod +x` it fails with `Permission denied`, the macro walks straight past it, and Script C's four `cp` lines then each report a missing file.
+* **The DSC scan shares the ports with `blanton_ber.sh`, `blanton_traffic_linespeed` and `blanton_tr518.sh`** — do not run it alongside any of them.
+* **Script 4 and Script 5 still use `pause`.** Only A, B and C were converted.

+# v1.2.1 — A BER baseline, so the SerDes numbers have something to be compared against
+
+## ✨ New features
+
+**Script A now takes a SerDes BER sweep before the first traffic run**
+* `blanton_ber.sh init → start → sleep 30 → report → stop → clear`, branched on `SWB_UNIT0` / `SWB_UNIT1` exactly like the traffic block beside it.
+* Script C already ran the closing sweep after its traffic report. With this one at the front, the pair brackets the soak — the same shape as the DSC scans added in v1.2.0, and the same reason: a BER figure on its own says very little, a *change* in it says a lot.
+* The `sleep 30` matches `blanton_ber.sh`'s `BER_INTERVAL`. Reporting before one full interval has accumulated reads a window that has not finished, and nothing warns you about it.
+
+## 🐛 Bug fixes
+
+**The new block's comment described the wrong position**
+* It was copied out of Script C, which runs BER *after* the traffic report, and the comment came with it and still said "after". In Script A the block runs *before* traffic. The comment now says what the code does and why the ordering is what it is.
+
+## ⚠️ Before you run
+
+* **Watch Script A's first traffic report on the first run.** PRBS holds the lanes out of normal operation and `blanton_ber.sh clear` is what releases them — and in Script A nothing settles between that `clear` and the `blanton_traffic_linespeed ps` / `init` that follows. Script C does not have this ordering, so the two reports are a built-in comparison: **if Script A shows NA or FAIL pairs that Script C does not, the lanes had not come back yet**, and a `sleep` after `clear` is the fix. This has not been run on hardware yet.
+* **`sleep 30` and `BER_INTERVAL` now live in three places** — Script A, Script C, and `blanton_ber.sh` itself. Changing one without the others silently reports a partial interval.
+* **BER, `blanton_traffic_linespeed` and `blanton_tr518.sh` cannot overlap.** They all take over the same ports. Script A now touches those ports twice before the soak even starts.
+* **`EN_TX_FIR` is still 0 by default**, so the DSC scans do not run unless you turn them on; a full scan is ~10 min in each of Script A and Script C.
+* **Replace `config.ttl` along with the macros.** Tera Term aborts the macro on an undefined variable rather than treating it as 0.
+* **`bcm_dsc_scan.sh` needs the execute bit**: `chmod +x ~/Blanton_Script/*.sh` after copying.
+* **`--runtime` is the job's overall limit, not a per-pass one.** `--passes` does not extend it.
+* **Script 4 has no teardown**: finish it with `blanton_tr518.sh stop` **and** `systemctl stop mlucas-amm`.
+* **Script 5 (reboot cycle) has no exit condition.** A 199-cycle / 60-hour run has now been analysed: PCIe AER stayed at 0, all 218 traffic pairs and all 864 lanes passed every cycle, and the BMC never reset. Two things it did surface — `bmc-first-enroll` does not exist on that BMC build, and NFC returned FAIL on every cycle.
+* **`blanton_multiphase_margin.sh save` is permanent**, and must not be mixed with `margin.sh`.
+* **`READ_VIN` and `READ_IIN` are still not in the ADPM12200 coefficient table.**
+* **The BMC USB service log only exists on the USB stick.**
+* **`FAN_SPEED` is 100.**
+* **Still unverified from v1.1.0**: the `ce0` ingress mirror, the 120 s settle in `blanton_tr518.sh`, and `test mode nr=no` on stop.
