Add basic SDEI support, implementing the software event 0 only for now.
This already allows hypervisors like Jailhouse to use SDEI for internal
signaling while passing the GICC through to the guest (see also IMX8).
With SDEI on, we overrun the SRAM and need to stay in DRAM. So keep SDEI
off by default.

When configuring the UART_BAUD_REG register, the function
console_a3700_core_init() currently only changes the baud divisor field,
leaving other fields to their previous value.
This is incorrect, because the baud divisor is computed with the
assumption that the parent clock rate is 25 MHz, and since the other
fields in this register configure the parent clock, which could have
been changed by U-Boot or Linux.
Fix this function to also configure the other fields so that the UART
parent clock is selected to be the xtal clock.
For example without this change TF-A prints only
ERROR: a3700_system_off needs to be implemented
followed by garbage after plat_crash_console_init() is called.
After applying this change instead of garbage it also print crash info:

Morello exhibits the behavior similar to Juno wherein CNTBaseN.CNTFRQ
can be written but does not reflect the value of the CNTFRQ register
in CNTCTLBase frame. This doesn't follow ARM ARM in that the value
updated in CNTCTLBase.CNTFRQ is not reflected in CNTBaseN.CNTFRQ.
Hence enable the workaround (applied to Juno) for Morello that updates
the CNTFRQ register in the Non Secure CNTBaseN frame.

UART parent clock is by default the platform's xtal clock, which is
25 MHz.
The value defined in the driver, though, is 25.8048 MHz. This is a hack
for the suboptimal divisor calculation
Divisor = UART clock / (16 * baudrate)
which does not use rounding division, resulting in a suboptimal value
for divisor if the correct parent clock rate was used.
Change the code for divisor calculation to
Divisor = Round(UART clock / (16 * baudrate))
and change the parent clock rate value to 25 MHz.
The final UART divisor for default baudrate 115200 is not affected by
this change.
(Note that the parent clock rate should not be defined via a macro,
since the xtal clock can also be 40 MHz. This is outside of the scope of
this fix, though.)

In iMX8MM it is possible to have two copies of bootloader in
SD/eMMC and switch between them. The switch is triggered either
by the BootROM in case the bootloader image is faulty OR can be
enforced by the user. To trigger that switch the
PERSIST_SECONDARY_BOOT bit should be set in GPR10 SRC register.
As the bit is retained after WARM reset, that permits to control
BootROM behavior regarding what boot image it will boot after
reset: primary or secondary.
This is useful for reliable bootloader A/B updates, as it permits
switching between two copies of bootloader at different offsets of
the same storage.
If the PERSIST_SECONDARY_BOOT is 0, the boot ROM uses address
0x8400 for the primary image. If the PERSIST_SECONDARY_BOOT is 1,
the boot ROM reads that secondary image table from address 0x8200
on the boot media and uses the address specified in the table for
the secondary image.
Secondary Image Table contains the sector of secondary bootloader
image, exluding the offset to that image (explained below in the
note). To generate the Secondary Image Table, use e.g.:
$ printf '\x0\x0\x0\x0\x0\x0\x0\x0\x33\x22\x11'
'\x00\x00\x10\x0\x0\x00\x0\x0\x0'
> /tmp/sit.bin
$ hexdump -vC /tmp/sit.bin
00000000 00 00 00 00
00000004 00 00 00 00
00000008 33 22 11 00 <--- This is the "tag"
0000000c 00 10 00 00 <--- This is the "firstSectorNumber"
00000010 00 00 00 00
You can also use NXP script from [1][2] imx-mkimage tool for
SIT generation. Note that the firstSectorNumber is NOT the offset
of the IVT, but an offset of the IVT decremented by Image Vector
Table offset (Table 6-25. Image Vector Table Offset and Initial
Load Region Size for iMX8MM/MQ), so for secondary SPL copy at
offset 0x1042 sectors, firstSectorNumber must be 0x1000
(0x42 sectors * 512 = 0x8400 bytes offset).
In order to test redundant boot board should be closed and
SD/MMC manufacture mode disabled, as secondary boot is not
supported in the SD/MMC manufacture mode, which can be disabled
by blowing DISABLE_SDMMC_MFG (example for iMX8MM):
> fuse prog -y 2 1 0x00800000
For additional details check i.MX 8M Mini Apllication Processor

expansion device chapter.

Added support for HW computed CRC using Arm ACLE intrinsics.
These are built-in intrinsics available for ARMv8.1-A, and
onwards.
These intrinsics are enabled via '-march=armv8-a+crc' compile
switch for ARMv8-A (supports CRC instructions optionally).
HW CRC support is enabled unconditionally in BL2 for all Arm
platforms.
HW CRC calculation is verified offline to ensure a similar
result as its respective ZLib utility function.
HW CRC calculation support will be used in the upcoming
firmware update patches.
