optee: Make TZDRAM config options contingent on CONFIG_OPTEE

Commit c7b3a7ee5351 ("optee: adjust dependencies and default values for
dram") makes the TZDRAM defines for OPTEE show up for all configs as a
side-effect. While not harmful its not what we really want.

This patch makes the following defines contingent on CONFIG_OPTEE=y

CONFIG_OPTEE_TZDRAM_BASE
CONFIG_OPTEE_TZDRAM_SIZE

Rightly, if you don't have CONFIG_OPTEE=y you don't care about the above
two defines.

It becomes difficult to use uboot 'nand' command to

need to be taken care of.

It is even difficult to use existing msx-nand.c driver by
incorporating BCB attributes like mxs_dma_desc does
because it requires change in mtd and nand command.

So, cmd_nandbcb implemented in arch/arm/mach-imx

BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.

On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
  1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks

for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally

blk: Invalidate block cache when switching hwpart

Some storage devices have multiple hw partitions and both address from
zero, for example eMMC.
However currently block cache invalidation only applies to block
write/erase.
This can cause a problem that data of current hw partition is cached
before switching to another hw partition. And the following read
operation of the latter hw partition will get wrong data when reading
from the addresses that have been cached previously.

To solve this problem, invalidate block cache after a successful
select_hwpart operation.

tools: mkenvimage: Always consider non-regular files

At the moment mkenvimage has two separate read paths: One to read from
a potential pipe, while dynamically increasing the buffer size, and a
second one using mmap(2), using the input file's size. This is
problematic for two reasons:
- The "pipe" path will be chosen if the input filename is missing or
  "-".  Any named, but non-regular file will use the other path, which
  typically will cause mmap() to fail:
  $ mkenvimage -s 256 -o out <(echo "foo=bar")
- There is no reason to have *two* ways of reading a file, since the
  "pipe way" will always work, even for regular files.

Fix this (and simplify the code on the way) by always using the method
of dynamically resizing the buffer. The existing distinction between
the two cases will merely be used to use the open() syscall or not.

tools: mkenvimage: Fix reading from slow pipe

It is perfectly fine for the read(2) syscall to return with less than
the requested number of bytes read (short read, see the "RETURN VALUE"
section of the man page). This typically happens with slow input
(keyboard, network) or with complex pipes.

So far mkenvimage expects the exact number of requested bytes to be
read, assuming an end-of-file condition otherwise. This wrong behaviour
can be easily shown with:
$ (echo "foo=bar"; sleep 1; echo "bar=baz") | mkenvimage -s 256 -o out -
The second line will be missing from the output.

Correct this by checking for any positive, non-zero return value.

board detection infrastructure introduced earlier to do the following:

1) Parse the AM654x EVM base board EEPROM and populate items like board
   name and MAC addresses into the TI common EEPROM data structure
   residing in SRAM scratch space

   card is found, parse the data such as additional Ethernet MAC
   addresses from its on-board EEPROM and populate into U-Boot
   accordingly

   containing a list of daugherboard-specific DTB overlays based on
   daughercards found.

This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
