VBT on Intel(R) systems is available via sysfs as
/sys/kernel/debug/dri/0/i915_vbt
However the size of this file reads as 0 causing
intelvbttool to fail. This patch implements incremental reads
with realloc for such cases or whenever the file size is not
available (e.g. reading from stdin).
After this patch is applied, intelvbttool can be used as follows:
sudo intelvbttool -f /sys/kernel/debug/dri/0/i915_vbt -d

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

The BL31 on RK3399 is split into multiple segments... the majority goes
into DRAM, but small parts must be put into SRAM and PMUSRAM. With
CB:31123 only the DRAM part was added to memlayout, so the SRAM parts
will not be correctly marked in bootmem and BL31 loading fails the
selfload check. This patch adds the remaining regions to fix the
problem.

For CFL and WHL, Microcode is being loaded from FIT. Both
supports the PRMRR/SGX feature. If This is supported the FIT
microcode load will set the msr (0x08b) with the Patch id one
less than the id in the microcode binary. This results in
Microcode getting reloaded again in bootblock and ramstage.
Avoid the microcode reload by checking for PRMRR support.
CFL and WHL CPU die are based on KBL CPU so we need to have
this check, where CNL CPU die is not based on KBL CPU so
skip this check for CNL.

The default mapping was probably copy-pasted from a random
board and disabled some interrupts (by implicitly clearing
some register bits).
We provide a new default mapping with some reasoning, that
tries to be most compatible (i.e. avoids to use PIRQ E-H
that are not shareable on some boards).
The following functions had their interrupt pin disabled
before:
o SATA 2 (explicitly, no board seems to enable the device)
o PCIe Root Port #4, #6-#8 (probably by accident)
PIRQs used before this change: A-D, F and H. After this
change: A-D.
