7dc60d81a1 arm, am335x, siemens: fix factoryset interpretation
a record could contain other records, so after an ">" (begin mark)
there not always come an end mark "<", instead a ">" is possible.
Take care of this.

fb384c4720 mtd: nand: omap_gpmc: Always use ready/busy pin
The functions to detect the state of the ready / busy signal is already
available but only used in the SPL case. Lets use it always, also for the
main U-Boot. As all boards should have this HW connection.

Testing on Siemens Draco (am335x) showed a small perfomance gain by using
this ready pin to detect the NAND chip state. Here the values tested on
Draco with Hynix 4GBit NAND:

Without NAND ready pin:

U-Boot# time nand read 80400000 0 400000

NAND read: device 0 offset 0x0, size 0x400000
4194304 bytes read: OK

time: 2.947 seconds, 2947 ticks

With NAND ready pin:

U-Boot# time nand read 80400000 0 400000

NAND read: device 0 offset 0x0, size 0x400000
4194304 bytes read: OK

time: 2.795 seconds, 2795 ticks

So an increase of approx. 5%.

e49631afa0 arm: am33xx: Handle NAND+I2C boot-device the same way as NAND
Re-map NAND&I2C boot-device to the "normal" NAND boot-device.
Otherwise the SPL boot IF can't handle this device correctly.
Somehow booting with Hynix 4GBit NAND H27U4G8 on Siemens
Draco leads to this boot-device passed to SPL from the BootROM.

With this change, Draco boots just fine into main U-Boot.

aac5450ea9 omap_hsmmc: Board-specific TWL4030 MMC power initializations
Boards using the TWL4030 regulator may not all use the LDOs the same way
(e.g. MMC2 power can be controlled by another LDO than VMMC2).
This delegates TWL4030 MMC power initializations to board-specific functions,
that may still call twl4030_power_mmc_init for the default behavior.

a70e157f30 configs: omap5_common : Boot rootfs from sd card by default
* Since the emmc isn't always programed trying to load the fs from the
  emmc causes boot failures/kernel panic.

* The current bootcmd is set to:
  bootcmd=run findfdt; run mmcboot;setenv mmcdev 1; setenv bootpart 1:2; \
  setenv mmcroot /dev/mmcblk0p2 rw; run mmcboot;

My guess is the env variables should be set so that sd card boot
(dt,kernel,fs) is the default and then fallback to emmc if it fails (no
sd card detected)

The current bootcmd attempts to set mmcroot to the sd card rootfs but
that code doesn't run due to mmcboot being ran early on.

A previous operation may have set the error flag, which must be cleared
before a new write operation can be issued.

ad5dd7ae4b mxs_ocotp: check for errors from the OTP controller after writing
The write operation may fail when trying to write to a locked area. In
this case the ERROR bit is set in the CTRL register. Check for that
condition and return an error.

d8d160e420 mxs_ocotp: prevent error path from returning success
The code may goto 'fail' upon error with 'ret' variable set to an error
code, but this variable was being overwritten by a final preparation
function to restore the HCLK, so success was (in general) returned even
after an error was hit previously.

With this change, the function may now return success even if the final
preparation function fails, but it's probably enough to print a message
because (if successful) the real programming of the fuses has already
completed.
