Mon Apr 19 16:29:51 CEST 2010
TNETV107X is a Texas Instruments SoC based on an ARM1176 core, and with a
bunch on on-chip integrated peripherals. This patch adds support for the
TNETV107X EVM board.
Signed-off-by: Cyril Chemparathy <cyril at ti.com>
---
v5: rebased on master in u-boot-arm.git (unchanged)
v4: rebased on next in u-boot-arm.git (unchanged)
v3: Added NAND MTDID comment in board config
v2: Added maintainers entry
v2: Fixed sort order in main makefile
v2: Remove board specific linker script
v2: Style fixes - multiline comments
v2: Replaced clk_get() with clk_get_rate()
