a6759e3dfc ARM: rmobile: gen2: Enable ACTLR[0] (Enable invalidates of BTB) to facilitate CVE_2017-5715 WA in OS
Enable CVE_2017_5715 mitigation on CPU0 on R-Car H2, M2W, M2N, V2H,
which all contain Cortex-A15 cores. R-Car E2 contains only Cortex-A7
cores and is not affected. Without this enabled, Linux kernel reports:

  CPU0: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable

With this enabled, Linux kernel reports:

  CPU0: Spectre v2: using ICIALLU workaround

NOTE: This by itself does not enable the workaround for other CPUs
      than CPU0 and may require additional kernel patches for the
      other CPUs in SMP configurations.

e9c891ff93 ARM: rmobile: Update V2H Blanche
The V2H Blanche port was broken since some time. This patch updates
the V2H Blanche port to use modern frameworks, DM, DT probing, SPL
for the preloading and puts it on par with the M2 Porter board.

NOTE: The port is missing support for I2C1 for DA9063 reset, since the
      I2C driver needs to be converted to DM and DT probing. That's not
      an issue for this patch though, since the reset was broken on Silk
      since forever.

0e592d0759 ARM: rmobile: Convert TPL to SPL
There is currently no use for building the SPL anymore, since the
SPI loader can easily be replaced by TPL and TPL does load U-Boot
directly. Upgrade TPL to SPL and replace what used to be SPL with
it. This way we build the U-Boot sources only twice, not thrice.

98a100e9a3 ARM: rmobile: Shrink the TPL
Shrink the TPL by using tiny printf and tiny memset by default.
This removes the biggest symbol -- vsnprintf_internal -- from
the TPL and reduces the text segment by about 2 kiB.

9a5483e9df ARM: rmobile: Add TPL support on R8A7791 M2 Porter
Add and enable TPL on M2 Porter. The TPL must fit into 16 kiB due
to the Gen2 BootROM restriction. The TPL is running from MERAM and
is capable of performing the initial initialization of PFC, Clock,
GPIO, LBSC, DBSC and QSPI NOR. DBSC is responsible for bringing up
the DDR DRAM access. The TPL is capable of loading the next stage,
U-Boot, from either SPI NOR or UART as a fallback. If either does
provide a valid U-Boot uImage, the system stops, which allows the
operator to load U-Boot ie. via JTAG and start it manually.

7ee37d0e0c ARM: rmobile: Convert Porter to SPL
Due to size limitations of the MERAM, switch U-Boot to SPL.
The SPL is loaded by the SPI_LOADER into MERAM and then loads
U-Boot proper into DRAM. This way U-Boot can freely grow in
size in DRAM, as there is plenty of it.

NOTE: To update U-Boot, first install u-boot.img to 0x140000 in SPI NOR,
      then use the Minimon to flash u-boot-spl.srec using ls,2,e6304000.
      To generate u-boot-spl.srec, use objcopy:
        arm-linux-gnueabi-objcopy -O srec spl/u-boot-spl u-boot-spl.srec
