* ddr_cmd2_ioctrl : offset 0x44E1140C
* ddr_data0_ioctrl: offset 0x44E11440
* ddr_data1_ioctrl: offset 0x44E11444
While the struct ddr_cmdtctrl has also some reserved bits in the beginning.
The struct is mapped to the address 0x44E11404. As a result "cm0ioctl" points
to the ddr_cmd1_ioctrl register, "cm1ioctl" to the ddr_cmd2_ioctrl and etc.
Registers ddr_cmd0_ioctrl and ddr_data0_ioctrl are never configured because

cmd_bootm.c: Correct BOOTM_ERR_OVERLAP handling
With
35fc84fa1 [Refactor the bootm command to reduce code duplication]
we stopped checking the return value of bootm_load_os (unintentionally!)
and simply returned if we had a non-zero return value from the function.
This broke the valid case of a legacy image file of a single kernel
loaded into an overlapping memory area (the default way of booting
nearly all TI platforms).
The best way to fix this problem in the new code is to make
bootm_load_os be the one to see if we have a problem with this, and if
it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so
that we can avoid calling lmb_reserve() but continue with booting. We
however still need to handle the other BOOTM_ERR values so re-work
do_bootm_states so that we have an error handler at the bottom we can
goto for problems from bootm_load_os, or problems from the other callers
(as the code was before). Add a comment to do_bootm_states noting the
existing restriction on negative return values.

Fix block device accesses beyond 2TiB
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives.
For some obscure reason, the current U-Boot code uses lbaint_t for the

sizes will evolve), but not for the starting address. Trying to access
blocks beyond the 2TiB boundary will simply wrap around and read a
block within the 0..2TiB range.
We now use lbaint_t for block start addresses, too. This required

Fix two issues with the calculation of pre_div and post_div:
1. pre_div: While the calculation of pre_div looks correct, to set the
CONREG[15-12] bits pre_div needs to be decremented by 1:
The i.MX 6Dual/6Quad Applications Processor Reference Manual (IMX6DQRM
Rev. 0, 11/2012) states:
CONREG[15-12]: PRE_DIVIDER
0000 Divide by 1
0001 Divide by 2
0010 Divide by 3
...
1101 Divide by 14
1110 Divide by 15
1111 Divide by 16
I.e. if we want to divide by 2, we have to write 1 to CONREG[15-12].
2. In case the post divider becomes necessary, pre_div will be divided by
16. So set pre_div to 16, too. And not 15.
Both issues above are tested using the following examples:
clk_src =
60000000 (60MHz, default i.MX6 ECSPI clock)
a) max_hz ==
23000000 (23MHz, max i.MX6 ECSPI read clock)

-> pre_div = 16 (divide by 16 => CONREG[15-12] == 15)
-> post_div = 1 (divide by 2 => CONREG[11- 8] == 1)
=> 60MHz / 32 = 1.875MHz SPI clock
c) max_hz ==
1000000 (1MHz)
-> pre_div = 16 (divide by 16 => CONREG[15-12] == 15)

key verification must go in with the public keys, in a place that
is protected from modification.
Add a -r option which tells mkimage to mark all keys that it uses
for signing as 'required'.
If some keys are optional and some are required, run mkimage several
times (perhaps with different key directories if some keys are very
secret) using the -F flag to update an existing FIT.

mkimage: Add -c option to specify a comment for key signing
When signing an image, it is useful to add some details about which tool
or person is authorising the signing. Add a comment field which can take
care of miscellaneous requirements.
