pxa: add support for palmtreo680 board
This patch adds support for the Palm Treo 680 smartphone. A quick overview of
u-boot implementation on the treo 680...
The treo 680 has a Diskonchip G4 nand flash chip. This device has a 2k region
that maps to the system bus at the reset vector in a NOR-like fashion so that it
can be used as the boot device. The phone is shipped with this 2k region
configured as write-protected (can't be modified) and programmed with an initial
program loader (IPL). At power-up, this IPL loads the contents of two flash
blocks to SDRAM and jumps to it. The capacity of the two blocks is not large
enough to hold all of u-boot, so a u-boot SPL is used. To conserve flash space,
these two blocks and the necessary number of subsequent blocks are programmed
with a concatenated spl + u-boot image. That way, the IPL will also load a
portion of u-boot proper, and when the spl runs, it relocates the portion of
u-boot that the IPL has already loaded, and then resumes loading the remaining
part of u-boot before jumping to it.
The default_environment is used (CONFIG_ENV_IS_NOWHERE) because I didn't think
that having a writable environment was worth the cost of a flash block, although
adding it would be straightforward. I abuse the CONFIG_EXTRA_ENV_SETTINGS
option to specify the usbtty for the console (CONFIG_SYS_CONSOLE_IS_IN_ENV).
Support for the LCD is included, but currently it is only useful for displaying
the u-boot splash screen. But if u-boot is built without the usbtty console, it
does display the auto-boot progress nicely.
