9260a8c818 feat(imx8m): make bl33 start configurable via PRELOADED_BL33_BASE
The TF-A does have a official PRELOADED_BL33_BASE define which is used
to tell the TF-A where to jump and that no bl33 loading is requied. Use
this to make the platform specific PLAT_NS_IMAGE_OFFSET configurable.

This becomes necessary if one would like to place the bl33 code to other
places.

dd108c3c1f feat(imx8mq): add the dram retention support for imx8mq
Add the dram retention support for i.MX8MQ. As there is
no enough ocram space available before entering TF-A,
so the timing info need to be copied from dram into ocram.

0445a4ab1f refactor(imx8mq): introduce BL31_SIZE
No functional change.

Introduce BL31_SIZE define and calculate the limits based on the
BL31_BASE and the BL31_SIZE define. Also make use of SZ_64K to make
it easier to read. This is required for later BL31 PIE support since
it drops the calculation based on the BL31_LIMIT and BL31_BASE.

21189b8e21 fix(imx8mq): correct architected counter frequency
Different from other i.MX SoCs, which typically use a 24MHz reference clock,
the i.MX8MQ uses a 25MHz reference clock. As the architected timer clock
frequency is directly sourced from the reference clock via a /3 divider this
SoC runs the timers at 8.33MHz.

9ce232fe98 feat(plat/imx8m): add SiP call for secondary boot
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
Reference Manual, 6.1.5.4.5 Redundant boot support for
expansion device chapter.

72196cbb66 plat: imx8mq: Implement IMX_SIP_GET_SOC_INFO
The manual documents that 0x3036006c should contains the soc revision
for imx8mq but this always reports A0. Work around this by parsing the
ROM header and checking if OCOTP register 0x40 is stuck at 0xff0055aa.

Determining this inside TF-A makes life easier for OS, see for example
this linux discussion: https://lkml.org/lkml/2019/5/3/465

The soc revision can also be useful inside TF-A itself, for example for
the non-upstream DDR DVFS "busfreq" feature is affected by 8mq erratas.

The clock for OCOTP block can be disabled by OS so only initialize soc
revision once at boot time.
