arm: mvebu: sata_mv failed to identify HDDs during cold start

During cold start, with some HDDs, mv_sata_identify() does not populate
the ID words on the 1st ATA ID command. In fact, the first ATA ID
command will only power up the drive, and then the ATA ID command
processing is lost in the process.

Tests with:

- Seagate ST9250320AS 250GB HDD and Seagate ST4000DM004-2CV104 4TB HDD.
- Zyxel NSA310S (Kirkwood 88F6702), Marvell Dreamplug (Kirkwood 88F6281),
 Seagate GoFlex Home (Kirkwood 88F6281), Pogoplug V4 (Kirkwood 88F6192).

Observation:

- The Seagate ST9250320AS 250GB took about 3 seconds to spin up.
- The Seagate ST4000DM004-2CV104 4TB took about 8 seconds to spin up.
- mv_sata_identify() did not populate the ID words after the call to
 mv_ata_exec_ata_cmd_nondma().
- Attempt to insert a long delay of 30 seconds, ie. mdelay(30_000), after
the call to ata_wait_register() inside mv_ata_exec_ata_cmd_nondma() did
not help with the 4TB drive. The ID words were still empty after that 30s
delay.

Patch Description:

- Added a second ATA ID command in mv_sata_identify(), which will be
executed if the 1st ATA ID command did not return with valid ID words.
- Use the HDD drive capacity in the ID words as a successful indicator of
ATA ID command.
- In the scenario where a box is rebooted, the 1st ATA ID command is always
successful, so there is no extra time wasted.
- In the scenario where a box is cold started, the 1st ATA command is the
power up command. The 2nd ATA ID command alleviates the uncertainty of
how long we have to wait for the ID words to be populated by the SATA
controller.

arm: imx8ulp: Enable full L2 cache in SPL

SRAM2 is half L2 cache and default to SRAM after system boot.
To enable the full l2 cache (512KB), it needs to reset A35 to make
the change happen.

So re-implement the jump entry function in SPL:
1. configure the core0 reset vector to entry (ATF)
2. enable the L2 full cache
3. reset A35
So when core0 up, it runs into ATF. And we have 512KB L2 cache working.

Simon Glass [Sun, 1 Aug 2021 18:05:23 +0000 (12:05 -0600)]
dm: core: Don't allow uclass use before ready

At present it is possible to call uclass_get() before driver model is
inited. In fact this happens on x86 boards which use Intel FSPv1, since
mrccache_get_region() tries to get the SPI flash device very early
during init.

This has always been undefined behaviour. Previously it generally worked,
i.e. returned an error code without crashing, because gd->uclass_root_s
is zeroed and the uclass can be added despite driver model not being
ready, due to the way lists are implemented. With the change to use a
gd->uclass_root pointer, this no-longer works. For example, it causes a
hang on minnowmax.

Fix this by adding a check that driver model is ready when uclass_get() is
called. This function is called in the process of locating any device, so
it is a good place to add the check.

This fixes booting on minnowmax.

Revert "arm: bootm: Disable LMB reservation for command line and board info on arm64"

This reverts commit 2359fa7a87848626bcbd3399e92c657595880cd7.

While the goal is valid and there is surely unused memory in that area,
we also have a lot of crucial things still located at the top-of-memory
while running lmb_alloc_base. Such things are the page table (tlb_addr),
relocated U-Boot and the active stack. Possibly more. So this patch was
premature, we will need relocations of those things first if we want to
use the range.

Fixes booting on the IOT2050, but likely also on other boards. It got
stuck on relocating the FDT - over the relocated U-Boot code.
