Provide u-boot console functions to access IO space registers. A no
thrills implementation, accessing one register at a time.
For example:
boot > iod 80
0080: 00000094
boot > iod.w 80
0080: 0094
boot > iod.b 80
0080: 94
boot > iow.b 0x80 12
boot > iod 0x80
0080: 00000012

This implements a library for accessing EDID data from an LCD panel.
This is used to obtain information about the panel such as its
resolution and type.
This is a tidied-up version of the original code pulled from
https://github.com/ynezz/u-boot-edid.
The changes we made are:
- removed bit fields in the struct;
- removed endianness cases in the struct;
- fixed some wrong definitions;
- fixed to fit 80 columns;
- fixed some code styles.

This new command supports hashing SHA1 and SHA256. It could be extended
to others such as MD5 and the CRC algorithms. The syntax is modeled on
those:
hash <algorithm> <address> <length> [*<dest_addr> | <dest_envvar>]
to calculate a hash, and:
hash -v <algorithm> <address> <length> [*<verify_addr> | <verify_envvar>]
to verify a hash.
Use CONFIG_CMD_HASH to enable the command, CONFIG_SHA1 to enable SHA1 and
CONFIG_SHA256 to enable SHA256.
The existing sha1sum command remains.

We have a SHA1 command and want to add a SHA256 command also. Instead of
duplicating the code, create a generic hash API which can process
commands for different algorithms.

strncasecmp() is present as strnicmp() but disabled. Make it available
and define strcasecmp() also. There is a only a small performance penalty
to having strcasecmp() call strncasecmp(), so do this instead of a
standalone function, to save code space.
Update the prototype in arch-specific headers as needed to avoid warnings.

In preparation for making the hash function common, we may as well use
const where we can.
Also add a watchdog version of the hashing function.

Gettime returns the current timer value. If CONFIG_SYS_HZ is defined
then the timer value is also converted to seconds.
Tegra20 (SeaBoard) # gettime
Timer val: 7754
Seconds : 7
Remainder : 754
sys_hz = 1000
There has been some discussion about whether this is useful enough to
be included in U-Boot. The following boards do not have CONFIG_SYS_HZ
defined:
M52277EVB
M52277EVB_stmicro
M53017EVB
M54418TWR
M54418TWR_nand_mii
M54418TWR_nand_rmii

This patch builds upon the recently introduced CBMEM console
feature of coreboot.
CBMEM console uses a memry area allocated by coreboot to store
the console output. The memory area has a certain structure,
which allows to determine where the buffer is, the buffer size
and the location of the pointer in the buffer. This allows
different phases of the firmware (rom based coreboot, ram based
coreboot, u-boot after relocation with this change) to keep
adding text to the same buffer.
Note that this patch introduces a new console driver and adds the
driver to the list of drivers to be used for console output, i.e.
it engages only after u-boot relocates. Usiong CBMEM console for
capturing the pre-relocation console output will be done under a
separate change.
>From Linux, run the cbmem.py utility (which is a part of the coreboot
package) to see the output, e.g.:
vvvvvvvvvvvvvvvvv
SCSI: AHCI 0001.0300 32 slots 6 ports ? Gbps 0xf impl SATA mode
flags: 64bit ilck stag led pmp pio
...
Magic signature found
Kernel command line: "cros_secure quiet loglevel=1 console=tty2...
^^^^^^^^^^^^^^^^^
Note that the entire u-boot output fits into the buffer only if
the coreboot log level is reduced from the most verbose. Ether
the buffer size will have to be increased, or the coreboot
verbosity permanently reduced.

When __BYTEORDER_HAS_U64__ is not defined, we got warning following:

/tmp/include/linux/byteorder/little_endian.h:71:2: warning: implicit declaration of function ‘__swab64p’
[-Wimplicit-function-declaration]
-----
Usually, __arch__swab64* required for __fswab64, __swab64p and __swab64s
is defined. Therefore, __BYTEORDER_HAS_U64__ is unnecessary.
This removes __BYTEORDER_HAS_U64__.

however, CONFIG_FSL_SATA_V2 is defined in asm/config_mpc85xx.h.
it will never take effective in the board configuration file for
this kind of code :
#ifdef CONFIG_FSL_SATA_V2
...
#endif
