When pressing the reset button on boot the system will enter the
recovery mode, this is done by setting a preboot command. Inside the
preboot command we will sleep and then check if the button is still
pressed, then tftp will be used to download the image and flash it. If
something fails after the DHCP state the network console will be
enabled.
LED0 is the "RF Active"/Yellow LED on the sysmobts-v2. We are not
using the 'yellow' LED alias as one needs to provide two functions
that call __led_set on led_yellow_on and led_yellow_off. Initialize
the GPIO direction in the board routine as the status_led code will
not be used.
The only ARM/kernel visible change is the change of the EEPROM. U-Boot
sadly does not support to select EEPROM with different page sizes and
address length. This is why we need to patch the common epprom code.
Introduce a new command to allow dynamic configuration of the EEPROM,
move the eeprom parameters into variables and change the code. This sadly
copies the SPI_X code as well. The address creation could be moved to
a different variable.
This code has been tested on RevC and RevD hardware and an IP address
could be obtained in both cases.
In commit abbab70 we added a prototype for hw_watchdog_init, in a
Freescale i.MX watchdog driver. We did not however guard it with an
__ASSEMBLY__ check and broke some platforms. Move this to the end of
the file with other prototypes and guard it.

Since commit de7d02aeb (mx6qsabresd: add usdhc2 and usdhc4 support)
SDHC3 device node is no longer 0, which breaks loading a uImage from SDHC3.
Fix it by adapting the default environment to use CONFIG_SYS_MMC_ENV_DEV as the
correct mmc node for loading the kernel from.
While at it, go back to using SDHC3 as the default mmc, since we have Yocto
images that generate an SD card containing U-boot,kernel and rootfs, so it is
more convenient to keep using SDHC3 as it was originally.

We enable console multiplexing and use both serial and LCD for stdout/stderr.
Initially, u-boot output console is observed via serial port.
If you also have a DP panel connected onto your SMDK5250 board,
you can switch to LCD console by typing "setenv stdout lcd".
You can always switch back to serial using "setenv stdout serial".
You can switch error console(stderr) as well, using similar commands.

IGEP board PC16550D (ns16550) UART doesn't set the
Transmitter Empty (TEMT) Bit in SPL. This makes
U-Boot to hang while waiting for TEMT. Add the

When booting an IGEPv2 board from NAND with SPL, U-Boot hangs
trying to read the OMAP General Purpose Memory Controller (GPMC).
The reason is that the GPMC initialization function is called
inside spl_board_init() and this function is only executed when
CONFIG_SPL_BOARD_INIT is defined.

Some boards want to report more than just memory size. For example, it
might be useful to display the memory type (DDR2, DDR3) or manufacturer.
Add a weak function to support this requirement, accessed through a new
'meminfo' command.

Add support for SST 4KB sector granularity.
Many recent SST flashes, i.e. SST39VF3201B and similar of this family
are declared CFI-conformant from SST. They support CFI query, but implement
2 different sector sizes in the same memory: a 64KB sector (they call it
"block", std AMD erase cmd=0x30), and a 4KB sector (they call it "sector",
erase cmd=0x50). Also, CFI query on these chips, reading from address 0x2dh
of cfi query struct, detects a number of secotrs for the 4KB granularity
(flinfo shows it).
For all other aspects, they are CFI compliant, so, as Linux do, i think
it's a good idea to handle these chips in the CFI driver, with a fixup
to allow 4KB granularity, as should be expected, instead of 64KB.

Move all the C runtime setup code from every start.S
in arch/arm into arch/arm/lib/crt0.S. This covers
the code sequence from setting up the initial stack
to calling into board_init_r().
Also, rewrite the C runtime setup and make functions
board_init_*() and relocate_code() behave according to
normal C semantics (no jumping across the C stack any
more, etc).
Some SPL targets had to be touched because they use
start.S explicitly or for some reason; the relevant

Also, even though the ROUND macro is already defined in common.h,
the reason for redefining it in image.h is explained by Stefano Babic:
"I will remark a previous comment - even if including common.h seems a
good idea to avoid duplications, it makes tools like mkimage to depend
on the selected board, because <board>_config must run. Even if this is
not a problem for us u-boot developers, it becomes an issue when these
tools are included in distros (like u-boot-tools in Ubuntu) and cannot
be packaged."
