Add the software workaround for ARM erratum ID 468414.

According to mx53/mx51 errata document:

"ENGcm11133 - ARM: NEON load data can be incorrectly forwarded to a
subsequent request

Description:

Under very specific set of conditions, data from a Neon load request can be incorrectly forwarded
to a subsequent, unrelated memory request.
The conditions are as follows:
• Neon loads and stores must be in use
• Neon L1 caching must be disabled
• Trustzone must be configured and in use
• The secure memory address space and the non-secure memory address space both use the same
physical addresses, either as an alias or the same memory location or for separate memory
locations
The issue is reported by ARM, erratum ID 468414, Category 2"

Since PLL2 now has changed, it is necessary to adapt the CONFIG_IPUV3_CLK
accordingly.

Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

Currently PLL2 is not explicitely configured for mx53 and it runs at 333MHz.

Since PLL2 is the parent clock for DDR2, IPU, VPU, we should set it at 400MHz
instead.

Without doing so, it is not possible to use a 2.6.35 FSL kernel and display HDMI
at 1080p because the IPU clock cannot reach the requested frequency.

Set PLL2 to 400MHz, so that 1080p can be played and the DDR2 can run at its
maximum frequency.

Also, setup the other PLL's as done in FSL U-boot and re-arrange the code a little
bit to allow easier comparison with the original clock setup from FSL U-boot.

init_clock is currently shared between mx51 and mx53 and it contains lots of

Adds support for HDMI, two LVDS panels and one RGB panel to
the SABRE-Lite board.

Displays supported:
         HDMI		- 1024 x 768 for maximum compatibility
         Hannstar-XGA   - 1024 x 768 LVDS (Freescale part number MCIMX-LVDS1)
         wsvga-lvds     - 1024 x 600 LVDS (Boundary p/n Nit6X_1024x600)
         wvga-rgb       - 800 x 480 RGB (Boundary p/n Nit6X_800x480)

Since the ipuv3_fb display driver currently supports only a single display,
this code auto-detects panel by probing the HDMI Phy for Hot Plug Detect
or the I2C touch controller of the LVDS and RGB displays in the priority
listed above.

Setting 'panel' environment variable to one of the names above will
override auto-detection.

The kernel from Freescale expects that the bootloader passes the board revision.

Read the board revision and pass it via get_board_rev().

Without passing the board revision the kernel does not operate properly as the
initialization of peripherals are different in revA versus revB boards.

On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not
suitable for the multi-instance use case (initialization made directly with
fsl_esdhc_initialize()).

clock frequency.

Each eSDHC instance has a dedicated clock.

gd->sdhc_clk must also be set accordingly. This is good for the case only a
single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A
future patch will fix the multi-instance use case (initialization made directly
with fsl_esdhc_initialize()).
