498d1a62db arm: socfpga: mmc: Pick the clock from clock manager
Make the SoCFPGA MMC stub pick clock via the clock manager
frequency accessors instead of hard-coding the frequency.

Also fix calloc() misuse.

832472a94d tools: socfpga: Add socfpga preloader signing to mkimage
Like many platforms, the Altera socfpga platform requires that the
preloader be "signed" in a certain way or the built-in boot ROM will
not boot the code.

This change automatically creates an appropriately signed preloader
from an SPL image.

The signed image includes a CRC which must, of course, be generated
with a CRC generator that the SoCFPGA boot ROM agrees with otherwise
the boot ROM will reject the image.

Unfortunately the CRC used in this boot ROM is not the same as the
Adler CRC in lib/crc32.c. Indeed the Adler code is not technically a
CRC but is more correctly described as a checksum.

Thus, the appropriate CRC generator is added to lib/ as crc32_alt.c.

1bf29b3d55 mmc: dw_mmc: Fix cache alignment issue
The DMA descriptors used by the DW MMC block must be aligned to cacheline
size, otherwise we are unable to properly flush/inval cache over them and
we get data corruption.

The reason I chose this approach of expanding the structure is because
the driver allocates the descriptors in bulk. This approach does waste
space by inserting slop inbetween the descriptors, but it makes access
to the descriptors easy as the compiler does know the real size of the
structure. It also makes cache operations easy, since the size of the
structure is cache aligned and the structure start address is as well.

be16aba5ce mtd: nand: Fix length bug in ioread16_rep() and iowrite16_rep()
The ioread16_rep() and iowrite16_rep() implementations are U-Boot specific
and have been introduced with the Linux MTD v3.14 sync. While introducing
these functions, the length for the loop has been miscalculated. The ">> 1"
is already present in the caller. So lets remove it in the function.

Tested on omap3_ha.

2f665945b3 mtd: nand: am335x: Fix 'bit-flip' errors in SPL
OMAP GPMC driver used with some NAND Flash devices
(e.g. Spansion S34ML08G1) causes that U-boot shows
hundreds of 'nand: bit-flip corrected' error messages.
Possible cause was discussed in the mailinglist thread:
http://lists.denx.de/pipermail/u-boot/2014-April/177508.html

The issue was partially fixed with the cc81a5291910d7a.git
however this has to be done to fix the SPL.

039b77396a powerpc: add --bss-plt to LDFLAGS
With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected)
it is necessary to specify --bss-plt to get the final blrl in the
_GOT2_TABLE_. Without this the last symbol does not get it's address
relocated.  For the P2041RDB board this ended up being
NetArpWaitTimerStart which caused the ARP packets to timeout
immediately.

c7eae7fcb1 board/ls1021aqds: Add DDR4 support
LS1021AQDS has a variant with DDR4 slot. This patch adds a new defconfig
for this variant to enable DDR4 support. RAW timing parameters are not
added for DDR4. The board timing parameters are only tuned for single-
rank 1600 and 1800MT/s with Micron DIMM 9ASF51272AZ-2G1A1 due to DIMM
availability.

f80d6472b4 driver/ddr/fsl: Fix DDR4 driver
When accumulated ECC is enabled, the DQ_MAP for ECC[4:7] needs to be set
to 0, i.e. 0->0, 1->1, etc., required by controller logic, even these pins
are not actually connected.

Also fix a bug when reading from DDR register to use proper accessor for
correct endianess.

8bfa301b0a ARMv8/ls2085a: Enable secondary cores
Spin table is at the very beginning of boot code. Each core has an individual
release address within the spin table, the ft_cpu_setup fn updates the
"cpu-release-addr" property of each cpu node with the corresponding release
address.

Also fix CPU_RELEASE_ADDR to point to secondary_boot_func.

40f8dec54d armv8/fsl-lsch3: Release secondary cores from boot hold off with Boot Page
Secondary cores need to be released from holdoff by boot release
registers. With GPP bootrom, they can boot from main memory
directly. Individual spin table is used for each core. Spin table
and the boot page is reserved in device tree so OS won't overwrite.

1d71efbb03 driver/ddr: Restruct driver to allow standalone memory space
U-boot has been initializing DDR for the main memory. The presumption
is the memory stays as a big continuous block, either linear or
interleaved. This change is to support putting some DDR controllers
to separated space without counting into main memory. The standalone
memory controller could use different number of DIMM slots.
