d622b08923 nxp: Rename board/freescale/common/Kconfig to arch/Kconfig.nxp
Now that board/freescale/common/Kconfig is safe to be included once,
globally, rename this to arch/Kconfig.nxp to better reflect that it
contains options that are valid on multiple architectures and SoC
families, and not specific to NXP reference platforms either.

93145335fb nxp: Make board/freescale/common/Kconfig safe to include once in arch/Kconfig
The way that we use this file currently means that we have to guard it
in every platform Kconfig.  But it is also required in all NXP
platforms, including non-reference platforms.  Make all options in it
have appropriate dependencies so that we can include it a single time
under arch/Kconfig

9167a1c28c powerpc: mpc85xx: Simplify jump to _start_cont in flash code
After more patches code for jumping to _start_cont symbol in flash memory
involved to code with useless mathematical operations. Currently it does:

  r3 := CONFIG_SYS_MONITOR_BASE + ABS(_start_cont) - CONFIG_SYS_MONITOR_BASE
  jump to r3

Which is equivalent of just:

  r3 := ABS(_start_cont)
  jump to r3

The purpose of that code is just to jump to _start_code symbol,
independently of program counter. So branch must be done to absolute
address. Trying to write:

  ba _start_cont

just cause linker error:

    LD      u-boot
  powerpc-linux-gnuspe-ld.bfd: arch/powerpc/cpu/mpc85xx/start.o: in function `switch_as':
  (.bootpg+0x4b8): relocation truncated to fit: R_PPC_ADDR24 against symbol `_start_cont' defined in .text section in arch/powerpc/cpu/mpc85xx/start.o
  make: *** [Makefile:1801: u-boot] Error 1

Probably by the fact that absolute address cannot be expressed by 24-bits.
So write the code via mtlr+blr pattern as it was before and load general
purpose register with absolute address of the symbol:

  lis     r3,_start_cont@h
  ori     r3,r3,_start_cont@l
  mtlr    r3
  blr

Seems that gcc and gnu ld linker support symbol@h and symbol@l syntax like
number@h and number@l without any problem. And disassembling of compiler
u-boot binary proved that lis+ori instructions are called with numbers
which represent halves of absolute address of _start_cont symbol.

bf8dae5fcf spi: cadence-qspi: reset qspi flash for versal platform
When flash operated at non default mode like DDR, flash need to be reset
to operate in SDR mode to read flash ids by spi-nor framework. Reset the
flash to the default state before using the flash. This reset is handled
by a gpio driver, in case of mini U-Boot as gpio driver is disabled, we
do raw read and write access by the registers.
Versal platform utilizes spi calibration for read delay programming, so
incase by default read delay property is set in DT. We make sure not to
use read delay from DT by overwriting read_delay with -1.

c0f4756216 powerpc: mpc85xx: Set TEXT_BASE addresses to real base values
Currently CONFIG_SPL_TEXT_BASE and CONFIG_SYS_TEXT_BASE addresses are
manually increased by 0x1000 due to .bootpg section. This section has size
of 0x1000 bytes and is manually put by linker script before .text section
(and therefore before base address) when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Due to this fact lot of other config options are manually increased by
0x1000 value to make correct layout. Note that entry point is not on
CONFIG_SPL_TEXT_BASE (image+0x1000) but it is really on address
CONFIG_SPL_TEXT_BASE-0x1000 (means at the start of the image).

Cleanup handling of .bootpg section when CONFIG_SYS_MPC85XX_NO_RESETVEC is
set. Put .bootpg code directly into .text section and move text base
address to the start of .bootpg code. And finally remove +0x1000 value from
lot of config options. With this removal custom PHDRS is not used anymore,
so remove it too.

After this change entry point would be at CONFIG_SPL_TEXT_BASE and not at
address -0x1000 anymore.

Tested on P2020 board with SPL and proper U-Boot.

aec051d813 microblaze: Remove interrupt handler
The primary purpose for this code was timer. By converting it to
CONFIG_TIMER there is no code which uses this implementation that's why
remove it. If there is a need to handle interrupts this patch can be
reverted in future.

a36d86720f microblaze: Convert axi timer to DM driver
Move axi timer driver from Microblaze to generic location.
Origin implementation was irq based with counting down timer.

CONFIG_TIMER drivers are designed differently that timer is free running up
timer with automatic reload without any interrupt.
Information about clock rates are find out in timer_pre_probe() that's why
there is no need to get any additional information from DT in the driver
itself (only register offset).

816226d27e cpu: add CPU driver for microblaze
Add a basic CPU driver that retrieves information about the microblaze CPU
core. cpu_ops handlers are implemented so that the "cpu" command can work
properly:

U-Boot-mONStR> cpu list
  0: cpu@0      MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
U-Boot-mONStR> cpu detail
  0: cpu@0      MicroBlaze @ 50MHz, Rev: 11.0, FPGA family: zynq7000
        ID = 0, freq = 50 MHz: L1 cache, MMU

Note: cpu_ver_lookup[] and family_string_lookup[] arrays were imported from
linux.

9df16c5937 microblaze: add support for handling PVR data
Add helper code for PVR (Processor Version Register) data handling. It
will be used by the UCLASS_CPU driver to populate cpuinfo fields at
runtime.

10f6508c07 microblaze: cache: introduce flush_dcache_range()
Align microblaze with the other architectures and provide an
implementation for flush_dcache_range(). Also, remove the microblaze
exception in drivers/core/device.c.

95b7a8fd12 microblaze: cache: introduce cpuinfo structure
Introduce a minimal cpuinfo structure to hold cache related info. The
instruction/data cache size and cache line size are initialized early in
the boot to default Kconfig values. They will be overwritten with data
from PVR/dtb if the microblaze UCLASS_CPU driver is enabled.

The cpuinfo struct was placed in global_data to allow the microblaze
UCLASS_CPU driver to also run before relocation (initialized global data
should be read-only before relocation).

gd_cpuinfo() helper macro was added to avoid volatile
"-Wdiscarded-qualifiers" warnings when using the pointer directly.

b195134984 microblaze: cache: introduce flush_cache_all()
All flush_cache() calls in microblaze code are supposed to flush the
entire instruction and data caches, so introduce flush_cache_all()
helper to handle this.

Also, provide implementations for flush_dcache_all() and
invalidate_icache_all() so that icache and dcache u-boot commands can
work.

instruction and data caches sizes, respectively:
CONFIG_XILINX_MICROBLAZE0_ICACHE_SIZE
CONFIG_XILINX_MICROBLAZE0_DCACHE_SIZE

Also, get rid of the hardcoded value in icache_disable().

Replace CONFIG_ICACHE with a Kconfig option more limited in scope -
XILINX_MICROBLAZE0_USE_WIC. It should be enabled if the processor supports
the "wic" (Write to Instruction Cache) instruction. It will be used to
guard "wic" invocations in microblaze cache code.
