a3d7cb1939 README: remove references on no more used config CONFIG_SYS_RCAR_I2C*
Remove the references in README on CONFIG_SYS_RCAR_I2C_* not use
in U-Boot drivers/i2c/rcar_i2c.c, since commit a4d9aafadb ("i2c:
 rcar_i2c: Remove the driver") and commit a06a0ac36d ("i2c: rcar_i2c:
 Add DM and DT capable I2C driver")

Checked by the command: grep -r SYS_RCAR_I2C *
And these CONFIG are only defined in
arch/arm/mach-rmobile/include/mach/rcar-base.h

4b4858936f lib: strto: Stop detection when invalid char is used
This issue has been found when mtd partition are specified. Autodetection
code should stop when the first invalid char is found.

Here is the example of commands:
setenv mtdids nand0=memory-controller@e000e000
setenv mtdparts "mtdparts=nand0:4m(boot),4m(env),64m(kernel),96m(rootfs)"
mtd list

  - min I/O: 0x800 bytes
  - OOB size: 64 bytes
  - OOB available: 16 bytes
  - ECC strength: 1 bits

Commit 6293b0361d ("mtd: nand: pxa3xx: add raw read support") added the
local data_len variable in handle_data_pio() to track read size, but
forgot to update the condition of drain_fifo() call. That happens to
work when the layout last_chunk_size != 0. But when last_chunk_size ==
0, drain_fifo() is not called to read the last chunk, which leads to
"Wait timeout!!!" error. Fix this.

6184858b85 arm: asm/cache.c: Introduce arm_reserve_mmu
As a preparation for turning reserve_mmu into an arch-specific variant,
introduce arm_reserve_mmu on ARM. It implements the default routine for
reserving memory for MMU TLB and needs to be weakly defined in order to allow
for machines to override it.

Without this decoupling, after introducing arch_reserve_mmu, there would be two
weak definitions for it, one in common/board_f.c and one in
arch/arm/lib/cache.c.

When moving the PHYLIB PHY drivers around in Kconfig we did not at the

enabling both the PHY driver and sub-option on the above referenced
platforms.

08140dba0f travis: Correct error checking when building boards
At present if buildman reports an error, the travis build still succeeds.

This is because the travis script does not stop when it sees errors; nor
does it automatically return the exit code. Also the current error
checking never triggers since 'ret' is not set.

ebfe611be9 mkimage: fit_image: Add option to make fit header align
The image is usually stored in block device like emmc, SD card, make the
offset of image data aligned to block(512 byte) can avoid data copy
during boot process.
eg. SPL boot from FIT image with external data:
- SPL read the first block of FIT image, and then parse the header;
- SPL read image data separately;
- The first image offset is the base_offset which is the header size;
- The second image offset is just after the first image;
- If the offset of imge does not aligned, SPL will do memcpy;
The header size is a ramdon number, which is very possible not aligned, so
add '-B size'to specify the align size in hex for better performance.

example usage:
  ./tools/mkimage -E -f u-boot.its -B 0x200 u-boot.itb

9e3c94d117 env/sf.c: drop private CMD_SAVEENV logic
Deciding whether to compile the env_sf_save() function based solely on
CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build
warning in case CONFIG_CMD_SAVEENV=n (because the env_save_ptr() macro
causes the function to indeed not be referenced anywhere). And for
SPL, when one selects CONFIG_SPL_SAVEENV, one obviously expects to
actually be able to save the environment.

1df96a7e76 env/ext4.c: remove CONFIG_CMD_SAVEENV ifdef
Removing this ifdef/endif pair yields a "defined but unused warning"
for CONFIG_CMD_SAVEENV=n, but that vanishes if we use the ENV_SAVE_PTR
macro instead. This gives slightly better compile testing, and
moreover, it's possible to have

  CONFIG_CMD_SAVEENV=n
  CONFIG_SPL_SAVEENV=y
  SPL_ENV_IS_IN_EXT4=y

in which case env_ext4_save would erroneously not be compiled in.

3908bc9344 env/fat.c: remove private CMD_SAVEENV logic
Always compile the env_fat_save() function, and let
CONFIG_IS_ENABLED(SAVEENV) (via the ENV_SAVE_PTR macro) decide whether
it actually ends up being compiled in.

82b2f41357 env_internal.h: add alternative ENV_SAVE_PTR macro
The current definition of the env_save_ptr does not take SPL_SAVEENV
into account. Moreover, the way it is implemented means that drivers
need to guard the definitions of their _save methods with ifdefs to
avoid "defined but unused" warnings in case CMD_SAVEENV=n.

The ifdeffery can be avoided by using a "something ? x : NULL"
construction instead and still have the compiler elide the _save
method when it is not referenced. Unfortunately we can't just switch
the existing env_save_ptr macro, since that would give a lot of build
errors unless all the ifdeffery is removed at the same time.
Conversely, removing that ifdeffery first would merely lead to the
"defined but unused" warnings temporarily, but for some storage
drivers it requires a bit more work than just removing their private
CMD_SAVEENV logic.

So introduce an alternative to env_save_ptr, which for lack of a
better name is simply uppercased, allowing one to update storage
drivers piecemeal to both reduce their ifdeffery and honour
CONFIG_SPL_SAVEENV.

1d0adee45c env: add SAVEENV as an alias of the CMD_SAVEENV symbol
Currently, testing whether to compile in support for saving the
environment is a bit awkward when one needs to take SPL_SAVEENV into
account, and quite a few storage drivers currently do not honour
SPL_SAVEENV.

To make it a bit easier to decide whether environment saving should be
enabled, introduce SAVEENV as an alias for the CMD_SAVEENV
symbol. Then one can simply use

  CONFIG_IS_ENABLED(SAVEENV)

df928f8549 bootcount_ext: Add flag to enable/disable bootcount
After a successful upgrade, multiple problem during boot sequence may
trigger the altbootcmd process.
This patch adds a version and an upgrade_available entries to the
bootcount file to enable/disable the bootcount check.
When failing to read the bootcount file it will consider that bootcount is
enabled, acting as previously, and update the file accordingly.

The bootcount file is only saved when `upgrade_available` is true, this
allows to save writes to the filesystem.

080019b86c make env_entry::callback conditional on !CONFIG_SPL_BUILD
The callback member of struct env_entry is always NULL for an SPL
build. Removing it thus saves a bit of run-time memory in the
SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded
in struct env_entry_node - i.e. about 2KB for the normal case of
512+change hash table entries.

Two small fixups are needed for this, all other references to the
callback member are already under !CONFIG_SPL_BUILD: Don't initialize
.callback in set_flags() - hsearch_r doesn't use that value
anyway. And make env_callback_init() initialize ->callback to NULL for
a new entry instead of relying on an unused or deleted entry having
NULL in ->callback.
