The Renesas RCar Gen2 chips have a mix of 32bit and 16bit variants
of the IP. There is no DT property which allows discerning those,
so what Linux does is it checks the size of the register area and
if it is 0x100, the IP is 16bit, otherwise the IP is 32bit. Handle
the distinction the same way.

Add support for 16bit mutation of the Matsushita SD IP. Since some

Factor out common code from the uniphier SD driver, change the prefix
of the functions from uniphier_sd_ to matsu_sd_ and create separate
renesas-sdhi.c driver. Thus far, all the code is still compiled when
CONFIG_UNIPHIER_MMC is selected and there is no functional change.
This patch is a preparation for further split of the SoC specific
parts of the Matsushita SD driver, used both on Uniphier and R-Car.

Add JTAG recovery support into the M2 Porter TPL. This allows the
TPL to be loaded over JTAG, initialize the system, wait for the
JTAG debugger to load U-Boot image into RAM and then resume and
start U-Boot from RAM.
The procedure is as follows:
1) Load u-boot-tpl.bin to 0xe6300000
2) Write magic number 0x1337c0de to 0xe6300020
TPL checks for this particular magic and starts JTAG recovery
if this number is present. This is not present by default.
3) Start U-Boot TPL from 0xe6300000
4) Wait for a message from TPL on UART indicating JTAG boot:
"JTAG boot detected!"
5) Halt the system in JTAG debugger
6) Load U-Boot image (u-boot.img) to 0x4fffffc0
7) Write magic number 0xb33fc0de to 0xe6300024
TPL checks for this particular magic to verify that the U-Boot
image was loaded into DRAM by the JTAG debugger.
8) Resume the system in JTAG debugger

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.

This patch fixes a situation where CONFIG_DM_SERIAL is enabled for
regular U-Boot and SPL, but not for TPL. In that case, the build
will try to include serial-uclass into the TPL nonetheless, because
CONFIG_DM_SERIAL is set.
The solution is to check if the build is for SPL or TPL and in that
case, check if CONFIG_$(SPL_TPL_)DM_SERIAL is also set. Only in that
case, include serial-uclass.c . If the build is for regular U-Boot,
CONFIG_BUILD is not set, so only check if CONFIG_DM_SERIAL is set
and if so, include serial-uclass.c

treewide: fix up files incorrectly marked executable
Joe Perches noted that we have a few source files that for some
inexplicable reason (read: I'm too lazy to even go look at the history)
are marked executable:
drivers/gpu/drm/amd/amdgpu/vce_v4_0.c
drivers/net/ethernet/cadence/macb_ptp.c
A simple git command line to show executable C/asm/header files is this:
git ls-files -s '*.[chsS]' | grep '^100755'
and then you can fix them up with scripting by just feeding that output
into:
| cut -f2 | xargs chmod -x
and commit it.
Which is exactly what this commit does.
