fc-loadtool help: improve language regarding 16 MiB flash chips
In FC project history, 16 MiB flash originally meant Pirelli DP-L10.
Then we got FCDEV3B with the same flash (our own design), but now we are
discovering more Calypso devices that used such large flash, both late
Calypso era (Sony Ericsson K2x0) as well as much earlier ones (FIC FLUID
devices.txt file with 2004 dates, Leonardo+ rev 5). Hence we need to
migrate to more generic or neutral language in associated documentation,
without giving elevated status to specific examples that drove our
early project history.

The "plain" version of compalstage selected below # should work for all C11x/12x; it will also work on C139/140 phones # that had the simpler boot code flashed into them, as we do with # FreeCalypso fw on these phones. When running loadtools with this config # on C139/140 phones that still have the official fw in them, one will need # to specify -h compal -c 1004 to use the inefficient ~15 KiB version of # compalstage. compal-stage plain # Whether we are breaking in through compalstage (as above) or through # tfc139, the re-enabled Calypso boot ROM is used to load our loadagent # into IRAM. The boot ROM will autodetect the Calypso input clock as # 26 MHz (physical reality) when entered through compalstage, or as # 13 MHz when entered through tfc139 - the latter results from the # original fw setting bit 7 in the FFFF:FD02 register (VTCXO_DIV2), # which the boot ROM does not clear. # # However, the following configuration will result in the ARM core # being clocked at 52 MHz in both cases. pll-config 4/1 rhea-cntl 0x00 # The remaining settings are carried out via loadagent commands init-script compal.init # Flash can be 2 MiB or 4 MiB, will be autodetected, 4 MiB mapping used # mapped at 0x03000000 like on other targets, see updated compal.init script flash single-4M 0x03000000 boot-reflash-hack 0x820000 0x10000 # Perform a Iota poweroff when we are done exit-mode iota-off
