Subject: [U-Boot] [PATCH 4/6] am33xx: Add am33xx_spl_board_init function, call
Date: Fri, 30 Aug 2013 16:28:44 -0400 [thread overview]
Message-ID: <1377894526-25517-4-git-send-email-trini@ti.com> (raw)
In-Reply-To: <1377894526-25517-1-git-send-email-trini@ti.com>
We need to allow for a further call-out in spl_board_init. Call this
am33xx_spl_board_init and add a __weak version. This function may be
used to scale the MPU frequency up, depending on board needs.
Signed-off-by: Tom Rini <trini@ti.com>

Changes in v2:
- Move am33xx_spl_board_init to am33xx/board.c from
omap-common/boot-common.c
