libserial-newlnx: ASYNC_LOW_LATENCY patch reverted
Reports from Das Signal indicate that loadtools performance on Debian
is about the same as on Slackware, and that including or omitting the
ASYNC_LOW_LATENCY patch from Serg makes no difference. Because the
patch in question does not appear to be necessary, it is being reverted
until and unless someone other than Serg reports an actual real-world
system on which loadtools operation times are slowed compared to the
Mother's Slackware reference and on which Slackware-like performance
can be restored by setting the ASYNC_LOW_LATENCY flag.

# Openmoko's GTA01/02 modem design is based on earlier Calypso phone or modem # designs by FIC, going back to 2004 according to dated comments in OM's FLUID # devices.txt file, and that parent design originally supported bigger flash # chips than the ones used in mass-produced GTA01/02 units. The latter have # Samsung K5A3240CTM or K5A3281CTM chips populated in them (4 MiB of flash, # 512 KiB or 1 MiB of RAM), but the PCB footprint actually fits a 16 MiB flash # chip (Spansion S71PL129J), with the second flash chip select wired to Calypso # nCS4. That devices.txt file also indicates that this nCS4 wiring was used # in FIC's 2004 design as well. # # This init script sets up Calypso MEMIF to access this maximum possibility of # 16 MiB of flash (in this particular wiring) or any subset thereof; it may be # needed if some early GTA01 prototype devices still had the bigger flash in # them or if someone finds an earlier (pre-Openmoko) FIC phone or modem. w16 fffffb00 00A4 w16 fffffb02 00A4 w16 fffffb0a 00A4 w16 fffef006 0008
