[U-Boot] [PATCH v5 3/3] TI: TNETV107X EVM initial support

Cyril Chemparathy cyril at ti.com
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()
