add support to read mac address for AM18x EVM manufactured from
Spectrum digital which have mac address stored in I2C EEPROM manufactured
by WINBOND. This patch reads mac address from I2C EEPROM and sets the
environment variable if not set, If mac address is already present in
environment compare it with the mac address in EEPROM and warn on
mismatch.Introduced a config option CONFIG_MAC_ADDR_IN_EEPROM to where
to look for the mac address.

this patch addresses the issue that there is no DVI output on beagleboard-xm in
u-boot; the TFP410 is not powered on, DVI_PUP needs to be set high
this is done differently on beagleboard-xm rev. B/C versus earlier boards:
beagleboard-xm B/C need to set GPIO2 of the TWL4030
earlier boards need to set GPIO170
note that the change occured somewhere inbetween beagleboard-xm rev. A2 and A3
note that beagleboard-xm rev. A and rev. B cannot be distinguished using
get_board_revision(), REVISION_XM_A/REVISION_XM_B is bogus
due to this glitch, the patch cannot work correctly on some beagleboard-xm
rev A/B boards
tested on beagleboard-xm rev. C (you should see orange color on a monitor)
note that the framebuffer is NOT yet set up, this could be done along the
lines below (for 800x480 resolution and RGB24) before calling omap3_dss_enable()
static void configure_frame_buffer() {
writel(0x80500000, (uint *) 0x48050480); // address
writel(0x80500000, (uint *) 0x48050484);

The commit message of a28afca (Add uboot "fdt_high" enviroment variable)
states that fdt_high behaves similarly to the existing initrd_high.
But fdt_high actually has an outstanding difference from initrd_high.
The former specifies the start address, while the later specifies the
end address.
As fdt_high and initrd_high will likely be used together, it'd be nice
to have them behave same. The patch changes the behavior of fdt_high
to have it aligned with initrd_high.
The document of fdt_high in README is updated with an example to
demonstrate the usage of this environment variable.

The default settings store the persistent environment on SD card
and not serial flash (SPI NOR).
To use SPI NOR to save the environment instead of SD card, edit
include/configs/mx6qsabrelite.h and
- undefine CONFIG_ENV_IS_IN_MMC
- define CONFIG_ENV_IS_IN_SPI_FLASH
The SPI driver can take as chip select the controller's chip selects
as well as an external GPIO. The LSB byte has the value of the internal
chip select, the highest (thought as 16-bit value) contains the GPIO
number.
The GPIO used on Sabre Lite is GP3:19 == 83.

The interface to the mxc_gpio driver uses integer (ordinal) values to
refer to all GPIOs on the i.MX processors. The registers themselves
and much of the i.MX documentation are banked in groups of 32, and these
macros allow the use of the port:index numbering for clarity.
GPIO_NUMBER() converts to ordinal value from port:index
GPIO_PORT() returns the port of an ordinal value
GPIO_INDEX() returns the index or offset of the ordinal.

This patch fixes booting i.MX28 CPUs via USB download.
In this mode the CPU's bootrom implements a USB HID device that
accepts a bootstream.
When downloading the bootstream via USB, first the SPL code is
received and executed. Then the u-boot image is received and
called.
The USB bootmode is interrupt driven.
This patch fixes two things:
1) The ARM's fast interrupt mode is disabled when the SPL code
has been run. So save and restore the CPSR register.
2) Save and restore c1 control register: the exception vector
location needs to be set back to bootrom space to make the USB
interrupts work again. The SPL code needs to change this
option for the ram size probing.

corresponding controller hardware.
With this reordering, we optain a proper interrupt

A MMC/SD card may always go into the programming state (and hence be
busy) after a block write. Therefore always check the card state, even
after single block writes. On the other hand there is no need to check
the card status after a read.
Also make sure that errors during busy polling are propagated upwards.

We are seeing occasional timeouts in the Tegra mmc code when
we are reading from external MMC cards. These don't seem to be
detrimental if they are handled properly. This CL properly
clears the "normal interrupt status register" (norintsts) in
error conditions. If we don't do this, when we come back into
mmc_send_cmd() the register will still contain status from the
last transaction.

Before we can send a command we need both the DATI (command inhibit on
mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear.
The previous behavior of only checking on DATI was insufficient on some
cards and incorrect behavior in any case. This makes the code check
for both bits being clear and makes the error print more clear as
to what happened. DATI_CMDDIS is removed as it was unused elsewhere
in the code and stood for 'DATI is set, cmds are disabled still'.
