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.

064057fdbe microblaze: Kconfig: introduce XILINX_MICROBLAZE0_FPGA_FAMILY option
Provide a static Kconfig value for the target FPGA archtitecture, as it is
done in Linux. The cpu-uclass driver will cross-check it with the value
read from PVR10 register.

84488fc693 microblaze: cache: introduce Kconfig options for icache/dcache sizes
Replace XILINX_DCACHE_BYTE_SIZE macro with two Kconfig symbols for
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().

8daf89678e microblaze: cache: improve icache Kconfig options
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.

ef0a592ae8 microblaze: cache: improve dcache Kconfig options
Replace CONFIG_DCACHE with a Kconfig option more limited in scope -
XILINX_MICROBLAZE0_USE_WDC. It should be enabled if the processor supports
the "wdc" (Write to Data Cache) instruction. It will be used to guard
"wdc" invocations in microblaze cache code.

Also, drop all ifdefs around flush_cache() calls and only keep one
CONFIG_IS_ENABLED() guard within flush_cache() itself.

Also, rename it to XILINX_MICROBLAZE0_DELAY_SLOT_EXCEP, since it only

b6aef10979 microblaze: add Kconfig symbol for the vector base address
MicroBlaze vector base address is configurable (hdl C_BASE_VECTORS
configuration parameter). Current code assumes that the reset vector
location is always 0x0.

Add the XILINX_MICROBLAZE0_VECTOR_BASE_ADDR Kconfig option so the user
can adjust the reset vector address.

461be2f96e kconfig: remove redundant "string" type in arch and board Kconfigs
Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME}
are specified in arch/Kconfig.

We can delete the ones in arch and board Kconfig files.

This commit can be easily reproduced by the following command:

find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e '
/config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ {
    N
    s/\n[[:space:]]*string//
}
'

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.
