The default reserved memory for CMA is high memory. If LPAE is enabled,
highmem pages are non-remapped and can not be used with
dma_alloc_coherent. This patch will reserve low memory for CMA and fix
the issue on LS1021A.

UniPhier SoC updates for v2020.04 (2nd)

Denali NAND driver changes:
 - Set up more registers in denali-spl for SOCFPGA
 - Make clocks optional
 - Do not assert reset signals in the remove hook
 - associate SPARE_AREA_SKIP_BYTES with DT compatible
 - switch to UCLASS_MTD

UniPhier platform changes:
 - fix a bug in dram_init()
 - specify loadaddr for "source" command

If the "source" command is not given the address, it uses
CONFIG_SYS_LOAD_ADDR, which is compile-time determined.

Using the "loadaddr" environment variable is handier because it is
relocated according to the memory base when CONFIG_POSITION_INDEPENDENT
is enabled.

Currently, the denali NAND driver in U-Boot configures the

Do likewise in U-Boot too.

The denali_spl.c still uses CONFIG_NAND_DENALI_SPARE_AREA_SKIP_BYTES.

When the reset signal is de-asserted, the HW-controlled bootstrap
starts running unless it is disabled in the SoC integration.
It issues some commands to detect a NAND chip, and sets up registers
automatically. Until this process finishes, software should avoid
any register access.

Without this delay function, some of UniPhier boards hangs up while
executing nand_scan_ident(). (denali_read_byte() is blocked)

The Denali NAND driver in mainline Linux currently cannot deassert the
reset. The upcoming Linux 5.6 will support the reset controlling, and
also set up SPARE_AREA_SKIP_BYTES correctly. So, the Denali driver in
the future kernel will work without relying on any bootloader or firmware.
However, we still need to take care of stable kernel versions for a while.
U-boot should not assert the reset of this controller.

Tested-by: Marek Vasut <marex@denx.de> # On SoCFPGA Arria V

Marek Vasut authored 5 years ago and Masahiro Yamada committed 5 years ago

On Altera SoCFPGA, upon either cold-boot or power-on reset, the
Denali NAND IP is initialized by the BootROM ; upon warm-reset,
the Denali NAND IP is NOT initialized by BootROM. In fact, upon
warm-reset, the SoCFPGA BootROM checks whether the SPL image in
on-chip RAM is valid and if so, completely skips re-loading the
SPL from the boot media.

This does sometimes lead to problems where the software left
the boot media in inconsistent state before warm-reset, and
because the BootROM does not reset the boot media, the boot
media is left in this inconsistent state, often until another
component attempts to access the boot media and fails with an
difficult to debug failure. To mitigate this problem, the SPL
on Altera SoCFPGA always resets all the IPs on the SoC early
on boot.

This results in a couple of register values, pre-programmed by
the BootROM, to be lost during this reset. To restore correct
operation of the IP on SoCFPGA, these values must be programmed
back into the controller by the driver. Note that on other SoCs
which do not use the HW-controlled bootstrap, more registers
may have to be programmed.

This also aligns the SPL behavior with the full Denali NAND
driver, which sets these values in denali_hw_init().

In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing
unaligned words" introduced changes to support unaligned reads for ARM
platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned
reads on ARM" improved the performance of these helpers.

In practice however, this only occurs when the user has forced the
device tree to be placed in memory in a non-aligned way, which in turn
violates both our rules and the Linux Kernel rules for how things must
reside in memory to function.

This "in practice" part is important as handling these other cases adds
visible (1 second or more) delay to boot in what would be considered the
fast path of the code.
