The 'sf' command is not supposed to rely on the MTD stack, but both

their location, these functions do not depend at all on the MTD
stack.
This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is
selected, which is inconsistent with the current situation. Solve this

ubi enhancements for 2020.01
- provide a way for skipping crc checks ported from linux, and add an
U-Boot command to set this flag on already installed systems.
- fix redundand environment management
U-Boot now supports the "skip_check" flag to optionally skip the CRC
check at open time. Currently its only possible to set this bit upon
UBI volume creation. But it might be very useful to also set this bit
on already installed systems (e.g. field upgrade) to make also use of
the boot-time decrease on those systems.
This patch now adds a new "ubi" command "ubi skipcheck" to set or clear
this bit in the UBI volume header:
=> ubi skipcheck rootfs0 on
Setting skip_check on volume rootfs0
BTW: This saves approx. 10 seconds Linux bootup time on a MT7688 based
target with 128MiB of SPI NAND.

Some users of static UBI volumes implement their own integrity check,
thus making the volume CRC check done at open time useless. For
instance, this is the case when one use the ubiblock + dm-verity +
squashfs combination, where dm-verity already checks integrity of the
block device but this time at the block granularity instead of verifying
the whole volume.
Skipping this test drastically improves the boot-time.

Since there is now a new version of the FSP and it is incompatible with
the existing version, move the code into an fsp1 directory. This will
allow us to put FSP v2 code into an fsp2 directory.
Add a Kconfig which defines which version is in use.
Some of the code in this new fsp1/ directory is generic across both FSPv1
and FSPv2. Future patches will address this.

Since this is part of the autoboot functionality, it makes sense to name
it with an AUTOBOOT prefix. No mainline boards use it so this should be
safe, and downstream boards will need to adjust.
Since this option is just an integer value, it really needs another option
to control whether the feature is enabled or not. Add a new
CONFIG_USE_AUTOBOOT_MENUKEY for that. This fits better with how things are
done with Kconfig, avoiding the need to use a specific value to disable

Quote from https://patchwork.ozlabs.org/patch/1104244/#2210814:
----------8<-----------
strncmp() is chosen for the sake of paranoid/defensive programming.
Indeed, strncmp() is not really needed when comparing a variable
with a string literal. We expect strcmp() to behave safely even if the
string variable is not NUL-terminated.
In the same scenario, Linux v5.2-rc7 uses both strcmp() and strncmp(),
but the frequency of strcmp() is higher:
$ git --version
git version 2.22.0
$ (Linux 5.2-rc7) git grep -En 'strncmp\([^"]*"[[:alnum:]]+"' | wc -l
1066
$ (Linux 5.2-rc7) git grep -En 'strcmp\([^"]*"[[:alnum:]]+"' | wc -l
1968
A quick "strcmp vs strncmp" object size test shows that strcmp()
generates smaller memory footprint (gcc-8, x86_64):
$ (U-Boot) size cmd/bcb-strncmp.o cmd/bcb-strcmp.o
text data bss dec hex filename
3373 400 2048 5821 16bd cmd/bcb-strncmp.o
3314 400 2048 5762 1682 cmd/bcb-strcmp.o
So, overall, I agree to use strcmp() whenever variables are compared
with string literals.

This sub-command serves for getting the partition index from
partition name. Also it can be used to test the existence of specified
partition.
Use case:
For example, in most CI environments this U-Boot command for automatic
testing of Linux rootfs is used:
=> setenv bootpart 1:f
where 0xf is "userdata" partition. But the number of "userdata"
partition can be changed any time, when partition table is changed.
So it would be nice to get rid of that 0xf magic number and use
partition name instead, like this:
=> part number mmc 1 userdata part_num
=> setenv bootpart 1:${part_num}

Adds UCLASS_MDIO DM class supporting MDIO buses that are probed as
stand-alone devices. Useful in particular for systems that support
DM_ETH and have a stand-alone MDIO hardware block shared by multiple
Ethernet interfaces.

Share the code that prints out a register field with the function that
prints out the "special" fields.
There were two arrays the register dump list, one with reg number and
name, another with a pointer to the field table and the table size.
These two arrays had have each entry match what register is referred to.
Combine them into just one table. Now they can't not match and there is
just one table.
Add some missing consts to pointers to string literals.
The dump code was ignoring the regno field in the description table and
assuming register 0 was at index 0, etc. Have it use the field.
Change reg > max+1 into reg >= max, which doesn't fail if max+1 could
overflow, besides just making more sense.

- mmc spi driver model support
- drop mmc_spi command
- enhanced Strobe mmc HS400 support
- minor mmc bug/fixes and optimization
- omap hsmmc and mvbeu update
- sdhci card detect support
The mmc_spi command was added to manually setup MMC over SPI bus
using command. This was required by the legacy non-DM MMC_SPI driver.
With DM based MMC_SPI driver in-place, we can now use all general
storge commands and mmc command for MMC over SPI bus hence we remove
the mmc_spi command all it's references.

Add sub-command 'env info' to display environment information:
- env_valid : is environment valid
- env_ready : is environment imported into hash table
- env_use_default : is default environment using
This command can be optionally used for evaluation in scripts:
[-d] : evaluate whether default environment is used
[-p] : evaluate whether environment can be persisted
The result of multiple evaluations will be combined with AND.

'Bootloader Control Block' (BCB) is a well established term/acronym in
the Android namespace which refers to a location in a dedicated raw
(i.e. FS-unaware) flash (e.g. eMMC) partition, usually called "misc",
which is used as media for exchanging messages between Android userspace
(particularly recovery [1]) and an Android-capable bootloader.
On higher level, this allows implementing a subset of Android Bootloader
Requirements [2], amongst which is the Android-specific bootloader
flow [3]. Regardless how the latter is implemented in U-Boot ([3] being
the most memorable example), reading/writing/dumping the BCB fields in
the development process from inside the U-Boot is a convenient feature.
Hence, make it available to the users.
Some usage examples of the new command recorded on R-Car H3ULCB-KF
('>>>' is an overlay on top of the original console output):
=> bcb
bcb - Load/set/clear/test/dump/store Android BCB fields
Usage:
bcb load <dev> <part> - load BCB from mmc <dev>:<part>
bcb set <field> <val> - set BCB <field> to <val>
bcb clear [<field>] - clear BCB <field> or all fields
bcb test <field> <op> <val> - test BCB <field> against <val>
bcb dump <field> - dump BCB <field>
bcb store - store BCB back to mmc
Legend:
<dev> - MMC device index containing the BCB partition
<part> - MMC partition index or name containing the BCB
<field> - one of {command,status,recovery,stage,reserved}
<op> - the binary operator used in 'bcb test':
'=' returns true if <val> matches the string stored in <field>
'~' returns true if <val> matches a subset of <field>'s string
<val> - string/text provided as input to bcb {set,test}
NOTE: any ':' character in <val> will be replaced by line feed
during 'bcb set' and used as separator by upper layers
=> bcb dump command
Error: Please, load BCB first!
>>> Users must specify mmc device and partition before any other call
=> bcb load 1 misc
=> bcb load 1 1
>>> The two calls are equivalent (assuming "misc" has index 1)
