Subject: [PATCH 05/18] ARMV7: Fix build for non-OMAP3 boards

Commit c3d3a54 uses CONFIG_ARMV7 to determine whether to call the
v7_flush_cache_all function.  This breaks the build for all non-OMAP3
boards (like Panda and OMAP4430SDP) since there is only a v7_flush_cache_all
implementation for OMAP3.

This patch uses CONFIG_OMAP3XXX instead of CONFIG_ARMV7 so that only boards
with a v7_flush_cache_all will make the call.

Tested on Beagle, Overo, Panda, and OMAP4430SDP

Subject: [PATCH 08/18] ARMV7: OMAP: Fix build after introduction of
 GENERATED_GBL_DATA_SIZE

This patch fixes the issue by defining and using CONFIG_SYS_INIT_RAM_SIZE and
CONFIG_SYS_INIT_RAM_ADDR. Based on an email discussion with Wolfgang Denk and
Heiko Schocher.

Subject: [PATCH 09/18] mmc: Clean up generic mmc driver multi-block write
 functions

The current mmc write implementation is type ulong, but returns int values.
Some of the printf's are terminated with /n/r, one has none.

This patch fixes these issues and also removes some unnecessary local
variables.

Subject: [PATCH 10/18] mmc: Add multi-block read support to the generic mmc
 driver

This patch adds multi-block read support for the generic MMC
driver. Large reads are broken into chunks of 65535 blocks to
ensure that the code works with controllers having a 16 bit block counter.

This patch results in a significant performance improvement.

Time to read a 45 MB file went from 36 seconds to 9 seconds on Overo

Subject: [PATCH 15/18] omap3evm: Fix mechanism to identify board revision

Function omap3_evm_get_revision() - to identify the
board revision was called at end of setup_net_chip().

Board revision can be ascertained only by identifying
the Ethernet chipset - but combining setup operations
with revision detection isn't a good idea. So, moved
the function after call to setup_net_chip().

Function setup_net_chip() should be ideally be called
only when CONFIG_CMD_NET is defined. But this leaves
the board revision "undetected". This patch allows
static definition of revision or default fallback to
the latest revision.

since commit 3667cbeed5e3c4067e624e52a916b1ebb02c8f05
on beagle board the second sdram bank didn;t longer
work. Since this patch sdram settings just get copied
from bank a, but CMD_NOP, CMD_PRECHARGE, CMD_AUTOREFRESH
are not executed and after that mr register is also
not updated. This patch adds this for the bank b.

From 858ecd9ac3434e011e84d5fd9013bd1ee199dbdc Mon Sep 17 00:00:00 2001
From: Albert Aribaud <albert.aribaud@free.fr>
Date: Mon, 15 Nov 2010 21:46:04 +0100
Subject: [PATCH 18/18] tx25: fix linker file for newer ld support

older ld emitted all ELF relocations in input sections named
.rel.dyn, whereas newer ld uses names of the form .rel*. The
linker script only collected .rel.dyn input sections. Rewrite
to collect all .rel* input sections.
