[U-Boot] [PATCH] Support for the Calao TNY-A9260/TNY-A9G20 boards
Albin Tonnerre
albin.tonnerre at free-electrons.com
Fri Jul 24 10:32:01 CEST 2009
The Calao TNY-A9260 and TNY-9G20 are boards manufactured and sold by Calao
Systems <http://www.calao-systems.com>. Their components are very
similar to the AT91SAM9260EK board, so their configuration is based on
the configuration of this board. There are however some differences:
different clocks, no LCD, no ethernet. They also uses SPI EEPROM to store
the environment.
The SPI chip is a STM95080, and as it's used in a number of CALAO boards
which should be supported soon, the corresponding spi_read and spi_write
functions have been put in drivers/spi/eeprom_m95xxx.c
Signed-off-by: Albin Tonnerre <albin.tonnerre at free-electrons.com>

Changelog since v1:
- Make the Makefile less verbose
- Add error checking for the result of get_ram_size
- Remove definition of the ROUND macro in configs/tny_a9260.h
- Move the MAINTAINERS entry to the correct place
- Add support for TNY-A9G20 in the process. The board is similar
to the TNY-A9260 except for the CPU, so this only adds a couple
ifdefs
- Minor formatting changes in comments
