This patch adds hab_auth_img_or_fail() a command line function that
encapsulates a common usage of authenticate and failover, namely if
authenticate image fails, then drop to BootROM USB recovery mode.
For secure-boot systems, this type of locked down behavior is important to
ensure no unsigned images can be run.
It's possible to script this logic but, when done over and over again the
environment starts get very complex and repetitive, reducing that script
repetition down to a command line function makes sense.

The tester registers provide a unique chip-level identifier which
get_board_serial() returns in a "struct tag_serialnr".
This patch documents the properties of the registers; in summary.
31:0 OCOTP_TESTER0 (most significant)
- FSL-wide unique, encoded LOT ID STD II/SJC CHALLENGE/ Unique ID
OCOTP_TESTER1 (least significant)
31:24
- The X-coordinate of the die location on the wafer/SJC CHALLENGE/ Unique
ID
23:16
- The Y-coordinate of the die location on the wafer/SJC CHALLENGE/ Unique
ID
15:11
- The wafer number of the wafer on which the device was fabricated/SJC
CHALLENGE/ Unique ID
10:0
- FSL-wide unique, encoded LOT ID STD II/SJC CHALLENGE/ Unique ID
The 64 bits of data generate a unique serial number per-chip.

When the DDR calibration is enabled, a situation may happen that it
will fail on a few select boards out of a whole production lot. In
particular, after the first write leveling stage, the MPWLDECTRLx
registers will contain a value 0x1nn , for nn usually being 0x7f or
slightly lower.
What this means is that the HW write leveling detected that the DQS
rising edge on one or more bundles arrives slightly _after_ CLK and
therefore when the DDR DRAM samples CLK on the DQS rising edge, the
CLK signal is already high (cfr. AN4467 rev2 Figure 7 on page 18).
The HW write leveling then ends up adding almost an entire cycle (thus
the 0x17f) to the DQS delay, which indeed aligns it, but also triggers
subsequent calibration failure in DQS gating due to this massive offset.
There are two observations here:
- If the MPWLDECTRLx value is corrected from 0x17f to 0x0 , then the
DQS gating passes, the entire calibration passes as well and the
DRAM is perfectly stable even under massive load.
- When using the NXP DRAM calibrator for iMX6/7, the value 0x17f or so
in MPWLDECTRx register is not there, but it is replaced by 0x0 as one
would expect.
Someone from NXP finally explains why, quoting [1]:
"
Having said all that, the DDR Stress Test does something that we
do not advertise to the users. The Stress Test iself looks at the
values of the MPWLDECTRL0/1 fields before reporting results, and
if it sees any filed with a value greater than 200/256 delay
(reported as half-cycle = 0x1 and ABS_OFFSET > 0x48), the DDR
Stress test will reset the Write Leveling delay for this lane
to 0x000 and not report it in the log.
The reason that the DDR Stress test does this is because a delay
of more than 78% a clock cycle means that the DQS edge is arriving
within the JEDEC tolerence of 25% of the clock edge. In most cases,
DQS is arriving < 5% tCK of the SDCLK edge in the early case, and
it does not make sense to delay the DQS strobe almost a full clock
cycle and add extra latency to each Write burst just to make the
two edges align exactly. In this case, we are guilty of making a
decision for the customer without telling them we are doing it so
that we don't have to provide the above explanation to every customer.
They don't need to know it.
"
This patch adds the correction described above, that is if the MPWLDECTRx
value is over 0x148, the value is corrected back to 0x0.

There is currently no use for building the SPL anymore, since the
SPI loader can easily be replaced by TPL and TPL does load U-Boot

it. This way we build the U-Boot sources only twice, not thrice.

Without armv8_setup_psci register VBAR_EL3 is not set up property which
makes SMC calls jump to invalid location.
smp_kick_all_cpus is required to make slave cpus leave gic_wait_for_interrupt.
Without this they will never pursue booting process.
Fix was applied to the two ways of booting VxWorks: bootvx and bootm commands.
This implementation is very similar to what is done in boot_jump_linux

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.

The at24 driver allows to register I2C EEPROM chips using different vendor
and devices, but the I2C subsystem does not take the vendor into account
when matching using the I2C table since it only has device entries.
But when matching using an OF table, both the vendor and device has to be
taken into account so the driver defines only a set of compatible strings
using the "atmel" vendor as a generic fallback for compatible I2C devices.
So add this generic fallback to the device node compatible string to make
the device to match the driver using the OF device ID table.
