bd25f9a69f mips: dts: Fix PIC32MZDA GPIO register definitions
The GPIO bank name for banks J and K are not correct when using the
'gpio' command from the console.

The driver derives the bank name from the device tree instance string by
using the instance value and adding 'A': gpio0@xxaddrxx is Bank A,
gpio1@yyaddryy is Bank B and so on.

On the PIC32, there is no Bank I so instances 8 and 9 need to be
incremented as a minimum change.

An alternative (less opaque) implementation would be to use a bank-name
property instead but this would require modifying the driver code too.

81b543a4e6 mips: dts: Fix PIC32MZDA GPIO register definitions
GPIO state cannot be changed via the device tree (e.g. with gpio-hog) or
using the 'gpio' command from the console.

The root cause is a discrepancy between the driver and the device tree:
the driver code expects an absolute I/O address in the <reg> property,
while the device tree defines the address relative to a declaration in
the parent pinctrl node.

Changing the device tree to fix a driver issue would normally be wrong,
however:
- I have run the first version of U-Boot in which this driver appears
  (v2016.03) and the same problem exists, so this is not a regression;
- There is no code that references a parent device tree node that might
  suggest the intent of the author was to parse the DT as it exists now;
- The equivalent Linux PIC32 GPIO driver also uses absolute addresses
  for the GPIO <reg> property. This change brings the U-Boot DT more
  into line with Linux.

Additionally, the data sheet (Microchip ref. 60001361H) shows that the
register set to control a GPIO bank spans 0xE0 bytes, but the device
tree specified size is only 0x48 bytes.

c372813105 mips: reloc: Change R_MIPS_NONE to catch pre-reloc BSS usage
This patch changes the R_MIPS_NONE define from 0 to a magic value. This
makes it possible to better detect any forbidden pre-relocation usage
of BSS variables, as they are often zero'ed and then relocation is
stopped too early.

Additionally the error message is improved to also print the faulting
address. This helps finding the root-cause for this breakage by
comparing this address with the values in System.map.

This patch helps a lot when working on pre-relocation code, like the

04d21a93fa mips: mt76x8: ddr_cal: Correct dqs_find_min/max implementations
The current implementations have some issues detecting the correct
values:

dqs_find_max() will return "last passing fieldval + 1" instead of
"last passing fieldval". Also it will return "maxval + 1" in the
case that all fieldvals are tested valid (without error).

dqs_find_min() will not test the "lowest" value because of using ">"
instead of ">=".

This patch now rewrites these functions to fix those issues. Also,
this patch uses the same approach of a for loop in both functions making
it easier to read and maintain.

Since the variables are integers now, we can use min()/max(), which
handles the wrap around case for fieldval=0: return (0 - 1).

7a4b6964b5 mips: mtmips: add SPL support
This patch adds SPL support for mtmips platform. The lowlevel architecture
is split into SPL and the rest parts are built into a memory loadable
u-boot image. Optional SPL_DM and OF_CONTROL are also supported.

The increment of size is very small (< 10 KiB) if SPL_DM and OF_CONTROL are
not enabled and the memory bootable u-boot (u-boot.img) is generated
automatically so there is not need to add a separate config for it.

A lzma compressed payload (u-boot-lzma.img) is also generated and it will
be combined with u-boot-spl.bin to form the unified ROM bootable binary
u-boot-mtmips.bin.

A spl loader is added to support uncompress the payload.

02cd449f0b mips: mtmips: rewrite lowlevel codes of mt7628
This patch rewrites the mtmips architecture with the following changes:

1. Move MT7628 soc parts into a subfolder.
2. Lock parts of D-Cache as temporary stack.
3. Reimplement DDR initialization in C language.
4. Reimplement DDR calibration in a clear logic.
5. Add full support for auto size detection for DDR1 and DDR2.
6. Use accurate CPU clock depending on the input xtal frequency for timer
   and delay functions.

Note:

print_cpuinfo() has incompatible parts with MT7620 so it's moved into
mt7628 subfolder.

a60c1e6d6b mips: add a mtmips-specific field to architecture-specific global data
SoCs of mtmips can use different CPU frequencies depending on the HW/SW
configurations. For example mt7628 uses 580MHz clock if the input xtal
frequency is 40MHz, and 575MHz clock if the xtal is 25MHz. Upon cold boot
the CPU uses the xtal frequency directly.

So hardcoding the timer frequency (half of the CPU frequency) in
CONFIG_SYS_MIPS_TIMER_FREQ is not a good idea for this case.

This patch adds a mtmips-specific field timer_freq to arch_global_data.
This field will be used later in mtmips-specific get_tbclk() to provide
accurate timer frequency in different boot stage.

6e9281b559 mips: start.S: avoid overwriting outside gd when clearing global data in stack
When setting up initial stack, global data will also be put in the stack,
and being cleared.

The assembler instructions for clearing gd is as follows:

	move	t0, k0
1:
	PTR_S	zero, 0(t0)
	blt	t0, t1, 1b
	 PTR_ADDIU t0, PTRSIZE

t0 is the start address of gd, t1 is the end address of gd (t0 + GD_SIZE).

[PTR_ADDIU t0, PTRSIZE] is in the delay slot of [blt t0, t1, 1b], so it
will be executed before the branch operation.

However the comparison for the BLT instruction is done before executing the
delay slot. This means when the last word just before k1 is cleared, the
loop will continue to run once. This will clear an extra word at k1, which
is outside the global data.

Global data is placed at the top of the stack. If the initial stack is a
SRAM or locked cache, the area outside them may be inaccessible. A write
operation performed in this area may cause an exception.

To solve this, [PTR_ADDIU t0, PTRSIZE] should be placed before the BLT
instruction.

fb9acad305 mips: cmd: go: Flush cache before jumping to app/image
It has been noticed on MT7628/88 platforms, that booting the RAM image
does not work reliably. Sometimes it works and sometimes not. Debugging
showed that this "might" be a cache related issue as very strange
errors occurred (e.g. output corrupted etc).

This patch adds a cache flush for the complete SDRAM area to the go cmd
before jumping to the entry point for the MIPS architecture. The
complete area is flushed as we don't know at this point, how big the
area of the "application" really is.

7048bb13b2 mips: vcoreiii: Fix cache coherency issues
This patch fixes an stability issue seen on some vcoreiii targets,
which was root caused to a cache inconsistency situation.

The inconsistency was caused by having kuseg pointing to NOR area but
used as a stack/gd/heap area during initialization, while only
relatively late remapping the RAM area into kuseg position.

The fix is to initialize the DDR right after the TLB setup, and then
remapping it into position before gd/stack/heap usage.

Commit f4dc714aaa ("arm64: Turn u-boot.bin back into an ELF file after
relocate-rela")
introduce REMAKE_ELF option to recreate u-boot.elf from u-boot ->
u-boot.bin + DT -> u-boot.elf.

The best is to ilustrate it from make V=1 output
  cat u-boot-nodtb.bin dts/dt.dtb > u-boot-dtb.bin
  cp u-boot-dtb.bin u-boot.bin
aarch64-linux-gnu-objcopy -I binary -B aarch64 -O elf64-littleaarch64  u-boot.bin u-boot-elf.o
  aarch64-linux-gnu-ld.bfd u-boot-elf.o -o u-boot.elf --defsym="_start"=0x8000000 -Ttext=0x8000000

Last command has no explicit linker script passed that's why toolchain
internal linker script is used.
In Binutils 2.32 case it contains SIZEOF_HEADERS symbol which has changed
behavior by commit
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=64029e93683a266c38d19789e780f3748bd6a188
which result in situation that program headers has changed from
(xilinx_zynqmp_mini_defconfig)

Program Headers:
  Type           Offset             VirtAddr           PhysAddr

Xilinx tools like XSDB or Bootgen are using program headers for loading ELF
to the right location and by above binutils change ELF is loaded to
incorrect location.

The patch is explicitly use u-boot-elf.lds (just cat now) for u-boot.elf
recreation which is called when REMAKE_ELF is setup.
By purpose u-boot-elf.lds doesn't contain OUTPUT_FORMAT/OUTPUT_ARCH to be
able to use by all archs.

2a250ae9b6 MIPS: remove Micronas VCT boards
The deadline for migration to CONFIG_DM is v2020.01. The VCT
baords would need an almost complete rewrite of all drivers to
support driver model.

Unless someone has access to the hardware and volunteers to do the migration,
the board should be scheduled for removal.

9814fb272f mips: mt76xx: Implement new d-cache fix in last_stage_init()
With commit 06985289d4 ("watchdog: Implement generic watchdog_reset()
version") the init sequence has changed in arch_misc_init(), resulting
in a re-appearance of the d-cache issue on MT7688 boards (e.g. gardena).
When this happens, the first (or sometimes later ones as well) TFTP
command hangs and does not complete correctly. This leads to the
assumption that the d-cache is not in a clean state once the ethernet
driver is called (d-cache is used here for the buffers). The old work-
around with the cache flush somehow does not work any more now with
the new code change.

Unfortunately adding CONFIG_SYS_MALLOC_CLEAR_ON_INIT also did not fix
this issue. With v2019.07-rc3 it shows again. The time of accessing
the data seems to be very important here. It needs to be "very late"
in the boot process.

Testing has shown, that copying a 64KiB area in DDR at a very late
bootup time, directly before calling into the prompt, fixes this issue.
Flushing of the complete d-cache does not seem to necessary, as this
copy alone seems to fix this problem.

To fix this issue, this patch now removes the old workaround and selects
CONFIG_SYS_MALLOC_CLEAR_ON_INIT for ARCH_MTMIPS. With this option the
complete malloc area is initialized with zeros (cache lines are touched).
Testing has shown that this also fixes the issue on the MT7688 boards.

6943cc9732 arch: mips: Update initrd_start and initrd_end
Microsemi SoC defines CONFIG_SYS_SDRAM_BASE to be 0x80000000, which
represents the start of kseg0 and represents a virtual address. Meaning
that the initrd_start and initrd_end point somewhere kseg0.
When these parameters are passed to linux kernel through DT
they are pointing somewhere in kseg0 which is a virtual address but linux
kernel expects the addresses to be physical addresses(in kuseg) because
it is converting the physical address to a virtual one.

Therefore update the uboot to pass the physical address of initrd_start
and initrd_end by converting them using the function virt_to_phys before
setting up the DT.

06985289d4 watchdog: Implement generic watchdog_reset() version
This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.

Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.

With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).

This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

2f41ade79e linker: Modify linker scripts to be more generic
Make use of "IMAGE_MAX_SIZE" and "IMAGE_TEXT_BASE" rather than
CONFIG_SPL_MAX_SIZE and CONFIG_SPL_TEXT_BASE.  This lets us re-use the
same script for both SPL and TPL.  Add logic to scripts/Makefile.spl to
pass in the right value when preprocessing the script.
