9ba5e5bc26 Revert "env: add spi_flash_read_env function"
This reverts commit 9a9d66f5ef.

because it breaks fw_setenv and U-Boot interworking, if
U-Boot environment is stored in a SPI-NOR.

Reproduce it with:
boot linux with empty Environment and store a variable
with fw_setenv into it, the Environment is now filled
with 0xff:

root@ckey5e:10:8e:~# hexdump -C /dev/mtd4
00000000  e9 e8 07 fa 01 62 6f 6f  74 63 6d 64 3d 72 75 6e  |.....bootcmd=run|
[...]
00000f30  7d 00 75 62 69 62 6f 6f  74 76 6f 6c 3d 32 00 00  |}.ubibootvol=2..|
00000f40  00 ff ff ff ff ff ff ff  ff ff ff ff ff ff ff ff  |................|

Boot now U-Boot prints:

Loading Environment from SPI Flash... SF: Detected s25fl128l with page size 256 Bytes, erase size 4 KiB, total 16 MiB
*** Warning - bad CRC, using default environment

Reason is the above commit, as it only reads until \0\0
is found, and assumes the rest of the Environment
space is filled with 0x00, which is not the case when
saving an Environment under linux with fw_setenv.

d46d27d3b6 MTD: mxs_nand_spl: Redo the way nand_init initializes
Currently the spl system calls nand_init which does nothing.
It isn't until an attempt to load from NAND that it gets initialized.
Subsequent attempts to load just skip the initialization  because
NAND is already initialized.

This moves the contents of mxs_nand_init to nand_init.  In the event
of an error, it clears the number of nand chips found.  Any
attempts to use nand will check if there are nand chips available
instead of actually doing the initialization at that time. If there
are none, it will return an error to the higher level calls.

e077b3ba4d warp7: Fix the write to the LDOGCTL PMIC register
The third parameter of the pmic_clrsetbits() function is the mask
to the register and the correct mask is 1 not 0.

Since the LDOGCTL only contains a single valid bit (bit 0),
we can use pmic_reg_write() and write 1 directly, which fixes
the problem in a simpler way and use the original pmic function
that was used prior to the DM PMIC conversion.

3eeb09b4c0 x86: Add efi runtime reset
Our selftest will soon test the actual runtime reset function rather than
the boot time one. For this, we need to ensure that the runtime version
actually succeeds on x86 to keep our travis tests work.

So this patch implements an x86 runtime reset function. It is missing
shutdown functionality today, but OSs usually implement that via ACPI
and this function does more than the stub from before, so it's at least
an improvement.

Eventually we will want to have full DM functionality in runtime services.
But this fixes a travis failure and doesn't clutter the code too heavily, so
we should pull it in without the amazing new RTS DM framework.

edf18a83f8 x86: acpi: Not every platform has serial console a first device
We may not do an assumption that current console device is always a first
of UCLASS_SERIAL one.

For example, on properly described Intel Edison board the console UART
is a third one.

Use current serial device as described in global data.

c652dd1557 x86: acpi: Add DMA descriptors for I2C1 on Intel Tangier
Intel Tangier SoC has a general purpose DMA which can serve to speed up
communications on SPI and I2C serial buses.

Provide DMA descriptors to utilize this capability in the future.

Note, I2C6, which is available to user, has no DMA request lines connected.
