7395398ad2 board_r - fixup functions table after relocation
This is only required for "PIC" relocation and doesn't apply to modern
"PIE" relocation which does data relocation as well as code.

"init_sequence_r" is just an array that consists of compile-time
adresses of init functions. Since this is basically an array of integers
(pointers to "void" to be more precise) it won't be modified during
relocation - it will be just copied to new location as it is.

As a consequence on execution after relocation "initcall_run_list" will
be jumping to pre-relocation addresses. As long as we don't overwrite
pre-relocation memory area init calls are executed correctly. But still
it is dangerous because after relocation we don't expect initially used
memory to stay untouched.

be6d426697 fdt_support.c: Correct linux,initrd-start/end setting
The change to add 64bit initrd support broke 32bit initrd support as it
always set 64bits worth of data into the properties, even on 32bit
systems.  The fix is to use addr_cell_len (which already says how much
data is in 'tmp') to set the property, rather than always setting 8.
Thanks to Stephen Warren for pointing out the fix here.

c5cbe1e299 bootm: Reinstate special case for standalone images
For standalone images, bootm had a special case where the OS boot function
was NULL but did actually exist. It was just called manually.

This was removed by commit 35fc84fa which checks for the non-existence of
this function before the special case is examined.

There is no obvious reason why standalone is handled with a special case.
Adjust the code so that standalone has a normal OS boot function. We still
need a special case for when the function returns, but at least we can
avoid the main problem.

This is intended to fix the reported:

    ERROR: booting os 'U-Boot' (17) is not supported

but needs testing.

ab71188ce8 mmc: add setdsr support
The eMMC and the SD-Card specifications describe the optional SET_DSR command.
During measurements at our lab we found that some cards implementing this feature
having really strong driver strengts per default. This can lead to voltage peaks
above the specification of the host on signal edges for data sent from a card to
the host.

Since availability of a given card type may be shorter than the time a certain
hardware will be produced it is useful to have support for this command (Alternative
would be changing termination resistors and adapting the driver strength of the
host to the used card.)

Following proposal for an implementation:

- new field that reflects CSD field DSR_IMP in struct mmc
- new field for design specific DSR value in struct mmc
- board code can set DSR value in mmc struct just after registering an controller
- mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set

Additionally the mmc command is extended to make is possible to play around with different
DSR values.

The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default
DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for
instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after
calling fsl_esdhc_initialize() for the eMMC.

This can be used to provide filesystem access within U-Boot to an ext2
image file on the host, for example.

The support is plumbed into the filesystem and partition interfaces.

We don't want to print a message in the driver every time we find a missing
device. Pass the information back to the caller where a message can be printed

9aed5a2777 board_f: explicitly disable console on early boot
If U-Boot build with DEBUG enabled/defined the first call of "debug"
function (that dumps data to any available console) will happen before
zeroing of initial "gd" in init call "zero_global_data" in
"init_sequence_f".

And if stack was not filled with zeros chances are high that
"gd->have_console" won't be 0. In its turn it will cause attempt to
output things to non-initialized yet serial console.

So for safety and predictability we set "gd->have_console = 0".

6ca6d080d6 cmd_eeprom: bug fix for i2c read/write
The local pointer of address (i.e., addr) only gets
referenced under SPI mode, and it won't be appropriate
to pass only 1-byte addr[1] to i2c_read/i2c_write while
CONFIG_SYS_I2C_EEPROM_ADDR_LEN > 1.

1. In U-boot's I2C model, the address would be re-assembled
   to a byte string in MSB order inside I2C controller drivers.

2. The 'CONFIG_SYS_I2C_EEPROM_ADDR_OVERFLOW' option which could
   be found at soft_i2c.c is always turned on in cmd_eeprom.c,
   the addr[0] always contains the device address with overflowed
   MSB address bits.

5b629319cf common/cmd_bootm.c: fix subcommand processing in OS specific do_bootm_xxx() functions
In commit "5c427e4: use BOOTM_STATE_OS_CMDLINE flag for plain bootm"
and "3d187b3: Only pass BOOTM_STATE_OS_CMDLINE on PowerPC/MIPS",
BOOTM_STATE_OS_CMDLINE was added to do_bootm for PowerPC and MIPS. This
breaks other OSes (vxworks, netbsd, plan9,...) that don't support
subcommand processing, e.g. they all contain the following code in their
do_bootm_xxx():

    if (flag & BOOTM_STATE_OS_PREP)
            return 0;
    if ((flag != 0) && (flag != BOOTM_STATE_OS_GO))
            return 1;

which will result a "subcommand not supported" error.
This patch changes the above logic to:

    /* if not go command, pretend everything to be OK */
    if (flag != BOOTM_STATE_OS_GO)
         return 0;
