In Cyclone 5 SoC platform, the first USB probing is failed but second
probing is success. DWC2 USB driver read gsnpsid register right after
de-assert reset, but controller is not ready yet and it returns gsnpsid 0.
Polling reset status after de-assert reset to solve the issue.Retry with this fix more than 10 times without issue.

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_MTDUniPhier 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.Signed-off-by: Masahiro Yamada

UCLASS_MTD is a better fit for NAND drivers.
Make NAND_DENALI_DT depend on DM_MTD, which is needed to compile
drivers/mtd/mtd-uclass.cAlso, make ARCH_UNIPHIER select DM_MTD because all the defconfig
of this platform enables NAND_DENALI_DT.Signed-off-by: Masahiro Yamada

Now that the reset controlling of the Denali NAND driver (denali_dt.c)
works for this platform, remove the adhoc reset deassert code.Signed-off-by: Masahiro Yamada
-
Currently, the denali NAND driver in U-Boot configures the
SPARE_AREA_SKIP_BYTES based on the CONFIG option.Recently, Linux kernel merged a patch that associates the proper
value for this register with the DT compatible string.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)Signed-off-by: Masahiro Yamada
-
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.Fixes: ed784ac3822b ("mtd: rawnand: denali: add reset handling")

The "nand_x" and "ecc" clocks are currently optional. Make the core
clock optional in the same way. This will allow platforms with no clock
driver support to use this driver.Signed-off-by: Masahiro Yamada
Tested-by: Marek Vasut # On SoCFPGA Arria V -
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().Signed-off-by: Marek Vasut

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.Cc: Patrice CHOTARD

All rockchip platforms support TPL or SPL-based bootloader
in mainline with U-Boot proper as final stage. For each
stage we need to burn the image on to flash with respective
offsets.This patch creates a single boot image component using
- binman, for arm32 rockchip platforms
- pad_cat, for arm64 rockchip platforms.This would help users to get rid of burning different
boot stage images.The new image called 'u-boot-rockchip.bin'
which can burn into flash like:₹ sudo dd if=u-boot-rockchip.bin of=/dev/sda seek=64
