This is adapted from the WIP SPI-MEM driver for the SFC on mainline

of the driver is that this one does not support DMA. In testing
the performance difference (performing a dual mode read on a 128Mb

arm: a37xx: pci: Fix handling PIO config error responses
Returning fabricated CRS value (0xFFFF0001) by PCIe Root Complex to OS is
allowed only for 4-byte PCI_VENDOR_ID config read request and only when
CRSSVE bit in Root Port PCIe device is enabled. In all other error PCIe
Root Complex must return all-ones.
So implement this logic in pci-aardvark.c driver properly.
aardvark HW does not have Root Port PCIe device and U-Boot does not
implement emulation of this device. So expect that CRSSVE bit is set as
U-Boot can already handle CRS value for PCI_VENDOR_ID config read request.
More callers of pci_bus_read_config() function in U-Boot do not check for
return value, but check readback value. Therefore always fill readback
value in pcie_advk_read_config() function. On error fill all-ones of
correct size as it is required for PCIe Root Complex.
And also correctly propagates error from failed config write request to
return value of pcie_advk_write_config() function. Most U-Boot callers
ignores this return value, but it is a good idea to return correct value
from function.
These issues about return value of failed config read requests, including
special handling of CRS were reported by Lorenzo and Bjorn for Linux kernel
driver pci-aardvark together with quotes from PCIe r4.0 spec, see details:

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.
- 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.
