19060bd886 ls102xa: esdhc: Add esdhc support for LS102xA
For LS1, esdhc is big-endian IP. Accessing the registers
should be in big-endian mode. So we use esdhc_read32()
to read Host controller capabilities register for LS1.

For LS1, when using CMD12, cmdtype need to be set to
ABORT, otherwise, next read command will hang.

c82e9de400 esdhc: Add CONFIG_SYS_FSL_ESDHC_LE and CONFIG_SYS_FSL_ESDHC_BE macros
For LS102xA, the processor is in little-endian mode, while esdhc IP is
in big-endian mode. CONFIG_SYS_FSL_ESDHC_LE and CONFIG_SYS_FSL_ESDHC_BE
are added. So accessing ESDHC registers can be determined by ESDHC IP's
endian mode.

52d00a812a ls102xa: etsec: Add etsec support for LS102xA
This patch is to add etsec support for LS102xA. First, Little-endian
descriptor mode should be enabled. So RxBDs and TxBDs are interpreted
with little-endian byte ordering. Second, TSEC_SIZE and TSEC_MDIO_OFFSET
are different from PowerPC, redefine them for LS1021xA.

93f26f130e net: Merge asm/fsl_enet.h into fsl_mdio.h
fsl_enet.h defines the mapping of the usual MII management
registers, which are included in the MDIO register block
common to Freescale ethernet controllers. So it shouldn't
depend on the CPU architecture but it should be actually
part of the arch independent fsl_mdio.h.

To remove the arch dependency, merge the content of
asm/fsl_enet.h into fsl_mdio.h.
Some files (like fm_eth.h) were simply including fsl_enet.h
only for phy.h. These were updated to include phy.h instead.

df0a5b880d ls102xa: i2c: Add i2c support for LS102xA
The existing i.MX's I2C driver mxc_i2c.c is compatible
with the controller of LS102xA. As I2C's registers
are 8-bit on LS102xA, I2C_QUIRK_REG is enabled to
use 8-bit driver.

This patch is to add I2C 1,2,3 support for LS102xA.

d60a2099a2 arm: ls102xa: Add Freescale LS102xA SoC support
The QorIQ LS1 family is built on Layerscape architecture,
the industry's first software-aware, core-agnostic networking
architecture to offer unprecedented efficiency and scale.

Freescale LS102xA is a set of SoCs combines two ARM
Cortex-A7 cores that have been optimized for high
reliability and pack the highest level of integration
available for sub-3 W embedded communications processors
with Layerscape architecture and with a comprehensive
enablement model focused on ease of programmability.

e30965db0c buildman: Separate out display of warnings and errors
Some boards unfortunately build with warnings and it is useful to be able
to easily distinguish the warnings from the errors.

Use a simple pattern match to categorise gcc output into warnings and
errors, and display each separately. New warnings are shown in magenta (with
a w+ prefix) and fixed warnings are shown in yellow with a w- prefix.

cc81a52919 mtd: nand: omap_gpmc: Fix 'bit-flip' errors
OMAP GPMC driver used with some NAND Flash devices (e.g. Spansion
S34ML08G1) causes that U-boot shows hundreds of 'nand: bit-flip
corrected' error messages. Possible cause was discussed in the
mailinglist thread:
http://lists.denx.de/pipermail/u-boot/2014-April/177508.html

Quote (Author: Pekon Gupta <pekon@ti.com>): "The issue is mainly
due to a NAND protocol violation in the omap driver since the
Random Data Output command (05h-E0h) expects to see only the
column address that should be addressed within the already loaded
read page into the read buffer. Only 2 address cycles with ALE
active should be provided between the 05h and E0h commands. The
Page read command expects the full address footprint (2bytes for
column address + 3bytes for row address), but once the page is
loaded into the read buffer, Random Data Output should be used
with only 2bytes for column address."

This patch combines the solution proposed in the mailinglist and
the patch provided by the Spansion company (GPLv2 code, source:

5c3f7e0ead mtd: nand: omap_gpmc: Enable multiple NAND flash devices
Since the CS of a device connected to the GPMC was
stored in the global variable, it was not possible to
use multiple devices. In this patch the CS is stored per
device in its 'struct omap_nand_info'. This makes it
possible to use up to 'GPMC_MAX_CS' NAND Flash devices
connected to U-boot.

fc12a1f589 mtd: nand: davinci_nand: correct keystone RBL layout definition
In case when 4K page keystone RBL layout is used the compilation
error is appeared. That's because the #ifdef has to be placed under
struct name. This patch correct it.
