Mon Nov 16 09:59:26 CET 2009


CM-T35 is a system-on-module board from CompuLab, Ltd. The CM-T35
datasheet can be found at
http://www.compulab.co.il/t35/html/t35-cm-datasheet.htm

Signed-off-by: Mike Rapoport <mike at compulab.co.il>

--
v2 changes:
- rename board config file from omap3_cm-t35.h to cm-t35.h
- remove SZ_xx references
- add MAKEALL/MAINTEINERS entries

v3 changes:
- fix whitespace and indentation
- remove eth_init from board_eth_init
- add CM-T35 entry to doc/README.omap3
- fixed board name in MAINTAINERS

v4 changes:
- rebased agains u-boot-ti/next branch

v5 changes:
- rename board files to cm_t35
- add explicit setup of GPMC with SMNAND configuration
- reorginize Ethernet initialization so that I2C related code will depend
on I2C initialization
