f63d638dad T4240/eth: fix SGMII card PHY address
QSGMII card assumed to be used by default, but if SGMII card is used,
it will use different PHY address, but we don't know which card is used
until we access PHY on the card. So we check the card type slot by slot,
if we can read a PHY ID by reading a SGMII PHY address on a slot, then
the slot must have a SGMII card pluged, we mark all ports on that slot,
and fix dts to use the SGMII card PHY address when doing dts fixup
for the marked ports.

545c12cf9a powerpc/p1_p2_rdb_pc: Add a pin to reset the DDR chip for P1021RDB-PC
When P1021RDB-PC reboot system, the board will hung at uboot DDR
configuration. For P1021RDB-PC DDR reset pin is multiplex with
QE, so uboot will reserve this pin for QE and skip DDR reset.
Other platforms without QE will do this reset. This patch adds
a slight code to reset DDR chip by QE CE_PB8 pin for NAND and
NOR FLASH boot. For booting from SPI FALSH and SD card, it
seems possible to use the rom on chip to write to the GPIO
pins before configuring the DDR.

Commit 3ebd1cbc introduced compiler-generated __bss_start
and __bss_end__ and commit c23561e7 rewrote all __bss_end__

7a3f481c6d i.MX6: mx6qsabrelite: README: don't pass chip-select to sf probe command
board/freescale/mx6qsabrelite/README explain a procedure to
update the SPI-NOR on the SabreLite board without Freescale
manufacturing tool but following this procedure leads to both
"sf erase" and "sf write" failing on a mx6qsabrelite board:

MX6QSABRELITE U-Boot > sf probe 1
MX6QSABRELITE U-Boot > sf erase 0 0x40000
SPI flash erase failed
MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000
SPI flash write failed

This is because the chip-select 1 is wrong and the correct
value is 0x7300.

Since commit c1173bd0 ("sf command: allow default bus and chip selects")
the chip-select and bus arguments for the sf probe command are optional
so let's just remove it and use "sf probe" instead.

38e7007725 mx6: Fix get_board_rev() for the mx6 solo case
When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev()
returns 0x62xxx, which is not a value understood by the VPU
(Video Processing Unit) library in the kernel and causes the video playback to
fail.

The expected values for get_board_rev are:
0x63xxx: For mx6quad/dual
0x61xxx: For mx6dual-lite/solo

So adjust get_board_rev() accordingly and make it as weak function, so that we
do not need to define it in every mx6 board file.

aad4659a2f mmc: i.MX6: fsl_esdhc: Define maximum bus width supported by a board
Maximum bus width supported by some i.MX6 boards is not 8bit like
others. In case where both host controller and card support 8bit transfers,
they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.

It is tested with a MMCplus card.

is encoded as 1 in MRS.LMR.MR0.A12 and MMDCx_MDSCR[28].

1791b1f97f imx: mx6q DDR3 init: Fix RST_to_CKE
MMDC1_MDOR.RST_to_CKE should be set to 500 µs according to the JEDEC
specification for DDR3. With a cycle of 15.258 µs, this gives 33 cycles encoded
as 0x23 for the bit-field MMDC1_MDOR[5:0].

MMDC1_MDOR.SDE_to_RST should be set to 200 µs according to the JEDEC
specification for DDR3. With a cycle of 15.258 µs, this gives 14 cycles encoded
as 0x10 for the bit-field MMDC1_MDOR[13:8].

aa53149e11 imx: mx6q DDR3 init: Fix tXPR
MMDC1_MDOR.tXPR should be set as specified for the JEDEC DDR3 timing tXPR.

For all DDR3 speed bins:
  tXPR(min) = max(5 nCK, tRFC(min) + 10 ns)
  tRFC(2 Gb) = 160 ns

All the users of mx6q_4x_mt41j128.cfg have a 2-Gb density (Micron
MT41J128M16HA-15E or SK hynix H5TQ2G63BFR-H9C for i.MX6Q SABRE Lite, and Micron
MT41K128M16JT-125:K for i.MX6 SABRE SD).

Hence, MMDC1_MDOR.tXPR should be set to max(5 nCK, 170 ns), which is 170 ns
and 91 nCK at 532 MHz, encoded as 0x5A in the bit-field MMDC1_MDOR[23:16].

6904e37746 imx: mx6q DDR3 init: Fix tMRD
MMDC1_MDCFG1.tMRD should be set to max(tMRD, tMOD) for DDR3.

For all DDR3 speed bins:
  tMRD(min) = 4 nCK
  tMOD(min) = max(12 nCK, 15 ns)

Hence, MMDC1_MDCFG1.tMRD should be set to max(12 nCK, 15 ns), which is 12 nCK
at 532 MHz, encoded as 0xB in the bit-field MMDC1_MDCFG1[8:5].

960aa89bda board/common: Add support for QIXIS read/write using i2c
QIXIS FPGA is accessable via both i2c and flash controller.
Only flash controller access is supported.

Add support of i2c based access. It is quite useful in the scenario
where either flash controller path is broken or not present.
