Add description of compiling u-boot for K230 CanMV.
Since the vendor's u-boot-spl verifies u-boot header [1], it is
necessary to use the Python script from vendor to add the header to the
u-boot image.

Add initial dts for K230-CanMV powered by Canaan Kendryte K230 SoC,
which has two RISC-V C908 cores, a big core with vector 1.0 extension
and a small core without vector extension.
This patch is basically comes from Linux Kernel [1] and it assumes
u-boot is running on the big core. Additionally, bootctl and reboot nodes
are added to support sysreset [2] and an clk_dummy node is added to
satisfy dependencies for usb [3].
Currently, u-boot is booted by the vendor's u-boot-spl. To meet the
requirements [4][5] of vendor's u-boot-spl for u-boot, a binman node with
mkimage child node is added here, which will compress u-boot.bin with
gzip and generate an image named "uboot" in the file u-boot-gz.img.

The RISC-V ISA profile RVA23U64 requires extension Zic64b (Cache blocks

This series provides a way to keep track of the images used in bootstd,
including the type of each image.
At present this is sort-of handled by struct bootflow but in quite an
ad-hoc way. The structure has become quite large and is hard to query.
Future work will be able to reduce its size.
Ultimately the 'bootflow info' command may change to also show images as
a list, but that is left for later, as this series is already fairly
long. So for now, just introduce the concept and adjust bootstd to use
it, with a simple command to list the images.
This series includes various alist enhancements, to make use of this new
data structure a little easier.
[trini: Drop patch 18 and 19 for now due to size considerations]

Use an alist for this data structure as it is somewhat simpler to
manage. This means that bootstd holds a simple list of bootflow structs

This list is only used by two functions, which can be updated to iterate
through the global list. Take this approach, which allows the bootdev
list to be dropped.
Overall this makes the code slightly more complicated, but will allow

This series implements fdt fixups, by reading hardware
information from registers and accordingly delete/modify
the DT nodes, at run-time.
Logs for AM62P boot:

The maximum frequency of the A53 CPU on the AM62P depends on the speed
grade of the SoC. This value is hardcoded in the DT for all AM62P
variants, potentially causing specifications to be exceeded. Moreover,
setting a common lower frequency for all variants increases boot time.
To prevent these issues, modify the DT at runtime from the R5 core to
adjust the A53 CPU frequency.

AM62P SoC has multiple speed grades. Add function to delete
non-relevant CPU frequency nodes, based on the information
retrieved from hardware registers. Fastest grade's maximum
frequency also depends on PMIC voltage, hence to simplify
implementation use the smaller value.

AM62Px2 (2 cores), AM62Px4 (4 cores)
-With and without CAN-FD & Video-codec support
Remove the relevant FDT nodes by reading the actual configuration
from the SoC registers, with that change it is possible to have a single
dts/dtb file handling the different variant at runtime.

size when ECC is enabled
As there are few redundant functions in board/ti/*/evm.c files, pull
them to a common location of access to reuse and include the common file
to access the functions.
Call k3-ddrss driver through fixup_ddr_driver_for_ecc() to fixup the
device tree and resize the available amount of DDR, if ECC is enabled.
Otherwise, fixup the device tree using the regular
fdt_fixup_memory_banks().
Also call dram_init_banksize() after every call to
fixup_ddr_driver_for_ecc() is made so that gd->bd is populated
correctly.
Ensure that fixup_ddr_driver_for_ecc() is agnostic to the number of DDR
controllers present.
