Cortex A78 erratum 1951500 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r1p1.  The workaround is to insert a DMB ST before
acquire atomic instructions without release semantics.  This workaround
works on revisions r1p0 and r1p1, in r0p0 there is no workaround.

Cortex A78 erratum 1941498 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r1p1.  The workaround is to set bit 8 in the ECTLR_EL1
register, there is a small performance cost (<0.5%) for setting this bit.

The current configuration of CPU windows on Armada 37x0 with 4 GB DRAM
can only utilize 3.375 GB of memory. This is because there are only 5
configuration windows, configured as such (in hexadecimal, also showing
ranges not configurable by CPU windows):

         0 - 80000000 |   2 GB | DDR  | CPU window 0
  80000000 - C0000000 |   1 GB | DDR  | CPU window 1
  C0000000 - D0000000 | 256 MB | DDR  | CPU window 2
  D0000000 - D2000000 |  32 MB |      | Internal regs
      empty space     |        |      |
  D8000000 - D8010000 |  64 KB |      | CCI regs
      empty space     |        |      |
  E0000000 - E8000000 | 128 MB | DDR  | CPU window 3
  E8000000 - F0000000 | 128 MB | PCIe | CPU window 4
      empty space     |        |      |
  FFF00000 - end      |  64 KB |      | Boot ROM

This can be improved by taking into account that:
- CCI window can be moved (the base address is only hardcoded in TF-A;
  U-Boot and Linux will not break with changing of this address)
- PCIe window can be moved (upstream U-Boot can change device-tree
  ranges of PCIe if PCIe window is moved)

Change the layout after the Internal regs as such:

  D2000000 - F2000000 | 512 MB | DDR  | CPU window 3
  F2000000 - FA000000 | 128 MB | PCIe | CPU window 4
      empty space     |        |      |
  FE000000 - FE010000 |  64 KB |      | CCI regs
      empty space     |        |      |
  FFF00000 - end      |  64 KB |      | Boot ROM

(Note that CCI regs base address is moved from D8000000 to FE000000 in
 all cases, not only for the configuration with 4 GB of DRAM. This is
 because TF-A is built with this address as a constant, so we cannot
 change this address at runtime only on some boards.)

This yields 3.75 GB of usable RAM.

Moreover U-Boot can theoretically reconfigure the PCIe window to DDR if
it discovers that no PCIe card is connected. This can add another 128 MB
of DRAM (resulting only in 128 MB of DRAM not being used).

Write char if fifo is empty. If this is done like this all chars are
printed. Because origin code just put that chars to fifo and in case of
reset messages were missing.

Before this change chars are put to fifo and only check before adding if
fifo is full. The patch is changing this logic that it is adding char only
when fifo is empty to make sure that in case of reset (by another SW for
example) all chars are printed. Maybe one char can be missed but for IP
itself it is much easier to send just one char compare to full fifo.

This patch provides the following changes in fixup_gdt_reloc()
function:
- Fixes assertions in processing dynamic relocations, when
relocation entries not matching R_AARCH64_RELATIVE type are found.
Linker might generate entries of relocation type R_AARCH64_NONE
(code 0), which should be ignored to make the code boot. Similar
issue was fixed in OP-TEE (see optee_os/ldelf/ta_elf_rel.c
commit 7a4dc765c133125428136a496a7644c6fec9b3c2)
- Fixes bug when "b.ge" (signed greater than or equal) condition
codes were used instead of "b.hs" (greater than or equal) for
comparison of absolute addresses.
- Adds optimisation which skips fixing Global Object Table (GOT)
entries when offset value is 0.

Introduce a new build option CM3_SYSTEM_RESET for A3700 platform, which,
when enabled, adds code to the PSCI reset handler to try to do system
reset by the WTMI firmware running on the Cortex-M3 secure coprocessor.
(This function is exposed via the mailbox interface.)

The reason is that the Turris MOX board has a HW bug which causes reset
to hang unpredictably. This issue can be solved by putting the board in
a specific state before reset.
