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. Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
