h2200 uses companion chip from Samsung. OneNAND ?
When device is powered on chip loads 16kb of flash into internal SRAM and PXA executes it. That program is 1st stage bootloader.
Check OneNAND SPL
I'm not sure I didn't checked yet.
But u-boot for my device has ~180kb. So it's to big for SRAM.
And I want to add driver for sdcard and flash and keyboard and lcd would be nice... So I will left it as it is for now.
these drivers are already in uboot
I haven't seen any MediaQ 1178 drivers (LCD).
oh it has separate LCD or it uses PXA LCDIF ?
MQ1178 is a separate SoC.
Also SD card and FLASH controllers are embedded in companion chip.
ASIC3 ?
Hamcop
Chip is based on S3C440 (or 410?) processor but needs some tweaks and tests.
Uhhh ?
Hamcop chip looks like s3c2440 processor without ARM core and with internal data busses limited to 16bytes. Really weird and buggy thing.
