4adef27013 fastboot: Implement OEM format only when we have MMC support
The current fastboot support assumes that CONFIG_FASTBOOT_FLASH implies
that we have an MMC in our system, which might not be the case if we have
some other storage device.

Change the configuration option protecting that call to
FASTBOOT_FLASH_MMC_DEV, that makes much more sense.

fc01daee8b sunxi: Add defconfig for the Sinovoip BPI-M2 board
The Sinovoip BPI-M2 is a SBC board based on the A31s SoC it features
1G RAM, a microsd slot, Gbit ethernet, 4 usb-a USB-2 ports, ir receiver,
stereo headphone jack and hdmi video output.

The dts changes are identical to the dts files submitted upstream.

A few notes on the use if dldo and aldo regulators. DLDO1 is used
for Vdd for the ethernet phy, ALDO2 is used for AVdd for the ethernet
phy. ALDO1 is used to power the sdio wifi module.

Add a bootcmd_sunxi_compat value to the default environment when building

to boot an old kernel can do so by simply typing "run bootcmd_sunxi_compat"

70ac9295e3 sunxi: Remove board defconfig-s for specific Q8 tablet PCB-s
We now have generic q8_a?3_defconfig files for Q8 formfactor tablets with
an A13 / A23 / A33 SoC, there is no need for these PCB variant specific
defconfig-s and they only serve to confuse the user.

Note that in case of the forfun_q88db_defconfig and TZX-Q8-713B7_defconfig
for A13 based Q8 tablets there is not even a dts file for these in the
upstream kernel, which is all the more reason to remove them.

The generic q8_a?3_defconfig files have been tested on an Et_q8_v1_6,
Ippo_q8h_v1_2_a33_1024x600, Ippo_q8h_v1_2 and TZX-Q8-713B7 tablet, and the
forfun_q88db_defconfig is identical to q8_a13_tablet_defconfig.

This leaves only the Ippo_q8h_v5 untested with the new generic defconfigs
but there is no reason to assume that it will not work.

dcfcb8d49a malloc_simple: Add support for switching to DRAM heap
malloc_simple uses a part of the stack as heap, initially it uses
SYS_MALLOC_F_LEN bytes which typically is quite small as the initial
stacks sits in SRAM and we do not have that much SRAM to work with.

When DRAM becomes available we may switch the stack from SRAM to DRAM
to give use more room. This commit adds support for also switching to
a new bigger malloc_simple heap located in the new stack.

Note that this requires spl_init to be called before spl_relocate_stack_gd
which in practice means that spl_init must be called from board_init_f.

Between v2015.07-rc1 and v2015.07-rc2 this board started
silent boot failure.  A bisect led to commit 6eed3786c6

looks harmless in itself, but it did implicitly add a feature
to the image which led to this:

i.e. we finally broke through the 256k monitor size.  Jump it
up to 384k and fix the hard coded value used in the env offset
at the same time.

We were probably flirting with the 256k size issue without
knowing it when testing on different baselines in earlier
commits, but since this is all board specific, a rebase or
reorder to put this commit 1st is of little value.

2727f3bfba dfu: dfu_sf: Take the start address into account
The dfu_alt_info_spl variable allows passing a starting point
for the binary to be flashed in the SPI NOR.

For example, if we have 'dfu_alt_info_spl=spl raw 0x400', this means
that we want to flash the binary starting at address 0x400.

In order to do so we need to erase the entire sector and write to
the the subsequent SPI NOR sectors taking such start address
into account for the address calculations.

Tested by succesfully writing SPL binary into 0x400 offset and
the u-boot.img at offset 64 kiB of a SPL NOR.

f4c9258213 dfu: dfu_sf: Use the erase sector size for erase operations
SPI NOR flashes need to erase the entire sector size and we cannot pass
any arbitrary length for the erase operation.

To illustrate the problem:

Copying data from PC to DFU device
Download    [=========================] 100%       478208 bytes
Download done.
state(7) = dfuMANIFEST, status(0) = No error condition is present
state(10) = dfuERROR, status(14) = Something went wrong, but the
device does not know what it was
Done!

In this case, the binary has 478208 bytes and the M25P32 SPI NOR
has an erase sector of 64kB.

478208  = 7 entire sectors of 64kiB + 19456 bytes.

Erasing the first seven 64 kB sectors works fine, but when trying
to erase the remainding 19456 causes problem and the board hangs.

Fix the issue by always erasing with the erase sector size.

This is as per the debug done by "Vitaly Andrianov <vitalya@ti.com>"
and based on the previous work done by "Hao Zhang <hzhang@ti.com>"

b9f06b360d arch/powerpc/config.mk: Pass -fno-ira-hoist-pressure when possible
There are various toolchain issues that cause us to produce invalid
binaries with certain gcc 4.8.x and 4.9.x versions when we don't pass
this flag in.

We need "u-boot,dm-pre-reloc" in the socfpga_cyclone5_socdk.dts file in
order for the SPL to use SD/MMC.

8d8e13e129 arm: socfpga: enable data/inst prefetch and shared override in the L2
Update the L2 AUX CTRL settings for the SoCFPGA.

Enabling D and I prefetch bits helps improve SDRAM performance on the
platform.

Also, we need to enable bit 22 of the L2. By not having bit 22 set in the
PL310 Auxiliary Control register (shared attribute override enable) has the
side effect of transforming Normal Shared Non-cacheable reads into Cacheable
no-allocate reads.

Coherent DMA buffers in Linux always have a Cacheable alias via the
kernel linear mapping and the processor can speculatively load cache
lines into the PL310 controller. With bit 22 cleared, Non-cacheable
reads would unexpectedly hit such cache lines leading to buffer
corruption.
