Enable GPMC's prefetch feature for NAND access. This speeds up NAND read
access a lot by pre-fetching contents in the background and reading them
through the FIFO address.
The current implementation has two limitations:
a) it only works in 8-bit mode
b) it only supports read access
Both is easily fixable by someone who has hardware to implement it.
Note that U-Boot code uses non word-aligned buffers to read data into, and
request read lengths that are not multiples of 4, so both partial buffers
(head and tail) have to be addressed.
Tested on AM335x hardware.

The ChromeOS EC keyboard is used by various different chromebooks. Peach
pi being the third board in the u-boot tree to use it (snow and peach
pit the other two). Rather then embedding the same big DT node in the
peach-pi DT again, copy the dtsi snippit & bindings documentation from
linux and include it in all 3 boards.
This slightly changes the dt bindings in u-boot:
* google,key-rows becomes keypad,num-rows
* google,key-colums becomes keypad,num-colums
* google,repeat-delay-ms and google,repeat-rate-ms are no longer used
and replaced by hardcoded values (similar to tegra kbc)

This patch adds documentation for Odroid-XU3. This documentation is
based on that of Odroid (doc/README-odroid) made by Przemyslaw Marczak.
The documentation includes basic information about boot media layout,
environment, partition layout, and the instruction to burn the u-boot
image to boot media.

This board sprinkles #ifdef(CONFIG_HERMES) over various global files
such as include/common.h, common/board_r.c, common/cmd_bdinfo.c.
Let's zap such an ill-behaved board.
It has not been converted to generic board yet and mpc8xx is old
enough.

fm_standard_init() initializes each 10G port by FM_TGEC_INFO_INITIALIZER.
but it needs different implementation of FM_TGEC_INFO_INITIALIZER on different SoCs.
on SoCs earlier(e.g. T4240, T2080), the notation between 10GEC and MAC as below:
10GEC1->MAC9, 10GEC2->MAC10, 10GEC3->MAC1, 10GEC4->MAC2
on SoCs later(e.g. T1024, etc), the notation between 10GEC and MAC as below:
10GEC1->MAC1, 10GEC2->MAC2
so we introduce CONFIG_FSL_FM_10GEC_REGULAR_NOTATION to fit the new SoCs on
which 10GEC enumeration is consistent with MAC enumeration.

Intel's Graphics Media Accelerator (GMA) is a generic name for a wide range
of video devices. Add code to set up the hardware on ivybridge. Part of the
init happens in native code, part of it happens in a 16-bit option ROM for
those nostalgic for the 1970s.
