8a42641a3e efi_selftest: SNP unit test on sandbox
Running the simple network protocol test on the sandbox requires setting
the environment variable ethact to a network interface connected to a DHCP
server and ethrotate to 'no'. So let's make it an on-request test on the
sandbox (selectable by setting environment variable efi_selftest).

056b45bc50 efi_loader: move efi_init_obj_list() to a new efi_setup.c
The function, efi_init_obj_list(), can be shared in different pseudo efi
applications, like bootefi/bootmgr as well as my efishell. Moreover, it
will be utilized to extend efi initialization, for example, my "removable
disk support" patch and "capsule-on-disk support" patch in the future.

So with this patch, it will be moved to a new file, efi_setup.c, under
lib/efi_loader and exported, making no changes in functionality.

23f5f4abf7 efi_loader: fix memory allocation on sandbox
Commit 7b78d6438a ("efi_loader: Reserve unaccessible memory") introduced
a comparison between RAM top and RAM start that was not known at the time
when the patch of commit 49759743bf ("efi_loader: eliminate sandbox
addresses") was written.

The sandbox uses an address space that is only relevant in the sandbox
context. We have to map ram_top from the sandbox address space to the
physical address space before using it in the EFI subsystem.

0ea8741ff6 efi_loader: CMD_BOOTEFI_HELLO_COMPILE in configs
It should not be necessary to adjust CMD_BOOTEFI_HELLO_COMPILE in config
files.

arch/arm/lib/crt0_arm_efi.S cannot be compiled in thumbs mode. We can
disable CMD_BOOTEFI_HELLO_COMPILE for CONFIG_CPU_V7M. So there is no longer
a need to disable it in stm32 configs.

helloworld.efi can be built without problems on x86_64. So there is no need
to disable it in chromebook_link64_defconfig and qemu-x86_64_defconfig.

Same is true for ARM V7A. So do not disable CMD_BOOTEFI_HELLO_COMPILE in
kp_imx6q_tpc_defconfig.

Some architecture checks are already make for EFI_LOADER. There is no need
to repeat them for CMD_BOOTEFI_HELLO_COMPILE

13dd6665ed distro: not taint environment variables if possible
The aim of this patch is not to have temporary variables used in
distro_bootcmd left as environment variables after run something.
See the discussion[1].
Without this patch, saveenv command also saves those variables, too.
While they are apparently safe, scsi_need_init can be harmful.

Please note that, in most cases, a variable should be converted to
hush's local variable, while "devplist" cannot because it is created
by "part" command as an environment variable.

synchronous mode with the CPU core clock rather than from an independent
PLL. We've seen this improve reliability in operation across a number of
boards and temperature ranges.

There is a need to find out the first free i2c ID which can be used for
i2s buses (including i2c buses connected to i2c mux). Do it early in
init and share this variable with other i2c classes for uniq bus
identification.

d3de38554a mmc: omap_hsmmc: Use regulator_set_enable_if_allowed for enabling regulator
Use regulator_set_enable_if_allowed() api instead of regulator_set_enable()
while enabling io regulators. This way the driver doesn't see an error
when disabling an always-on regulator and when enabling is not supported.

cc4a224af2 power: regulator: Introduce regulator_set_enable_if_allowed api
regulator_set_enable() api throws an error in the following three cases:
- when requested to disable an always-on regulator
- when set_enable() ops not provided by regulator driver
- when enabling is actually failed.(Error returned by the regulator driver)

Sometimes consumer drivers doesn't want to track the first two scenarios
and just need to worry about the case where enabling is actually failed.
But it is also a good practice to have an error value returned in the
first two cases.

So introduce an api regulator_set_enable_if_allowed() which ignores the
first two error cases and returns an error as given by regulator driver.
Consumer drivers can use this api need not worry about the first two
error conditions.
