23f3e399de pxe_utils: Fix arguments to x86 zboot
bootm and zboot accept different arguments:

> bootm [addr [arg ...]]
>    - boot application image stored in memory
>        passing arguments 'arg ...'; when booting a Linux kernel,
>        'arg' can be the address of an initrd image

> zboot [addr] [size] [initrd addr] [initrd size] [setup] [cmdline]
>       addr -        The optional starting address of the bzimage.
>                     If not set it defaults to the environment
>                     variable "fileaddr".
>       size -        The optional size of the bzimage. Defaults to
>                     zero.
>       initrd addr - The address of the initrd image to use, if any.
>       initrd size - The size of the initrd image to use, if any.

In the zboot flow, the current code will reuse the bootm args and attempt
to pass the initrd arg (argv[2]) as the kernel size (should be argv[3]).
zboot also expects the initrd address and size to be separate arguments.

Let's untangle them and have separate argv/argc locals.

1833e68c4f cmd: usb_mass_storage: Use part_get_info_by_dev_and_name_or_num
This allows specifying partitions using more extended syntax. This is
particularly useful to access eMMC hardware partitions. For example,
this allows something like

	ums 0 mmc 0.0,0.1,0.2,0.3

to expose four LUNs for each of the four default eMMC hardware
partitions. Note that the comma syntax was already present, and this
syntax is already documented.

f702dc1e1f cmd: mmc: Support mmc hwpartition user enh start -
Add option to extend the hardware partition to the maximum size by
using the '-' dash sign instead of $cnt parameter. This is useful
in case we want to switch the entire eMMC user area into pSLC mode,
especially in case the device may be populated with different size
eMMCs. With this change, we do not have to calculate the number of
blocks of the user area manually.

To switch the pSLC mode for user area, use e.g. the following.

0d1ecc99cb mtd: Remove mtd_erase_callback() entirely
The original purpose of mtd_erase_callback() in Linux at the time it was
imported to U-Boot, was to inform the caller that erasing is done (since
it was an asynchronous operation).

All supplied callback methods in U-Boot do nothing, but the
mtd_erase_callback() function was (until previous patch) grossly abused
in U-Boot's mtdpart implementation for completely different purpose.

Since we got rid of the abusement, remove the mtd_erase_callback()
function and the .callback member from struct erase_info entirely, in
order to avoid such problems in the future.

f231566475 env: Move non-cli env functions to env/common.c
Move the following functions from cmd/nvedit.c to env/common.c:
  env_set_ulong()
  env_set_hex()
  env_get_hex()
  eth_env_get_enetaddr()
  eth_env_set_enetaddr()
  env_get()
  from_env()
  env_get_f()
  env_get_ulong()
since these functions are not specific for U-Boot's CLI.

We leave env_set() in cmd/nvedit.c, since it calls _do_env_set(), which
is a static function in that file.

a80652ebb3 env: Simplify env_match() and inline into env_get_f()
In the past the env_match() function was used to match envs with
- name, i.e. string "name"
- variable assignment, i.e. string "name=other_value"

The latter is not the case anymore, since the env_match() function is
now used only in env_get_f(), and so we can simplify the function into
a simple strncmp() with an additional comparison to '='.

Let's do this, and since the resulting function is quite simple, let's
also inline its code into env_get_f().

3112ce0ce8 env: Make return value of env_get_f() behave like sprintf() on success
Currently the env_get_f() function's return value behaves weirdly: it
returns the number of bytes written into `buf`, but whether this is
excluding the terminating NULL-byte or including it depends on whether
there was enough space in `buf`.

Change the function to always return the actual length of the value of
the environment variable (excluding the terminating NULL-byte) on
success. This makes it behave like sprintf().

All users of this function in U-Boot are compatible with this change.

52f9ed34cb env: Inline env_get_char() into its only user
This function is a relic from the past when environment was read from
underlying device one character at a time.

It is used only in the case when getting an environemnt variable prior
relocation, and the function is simple enough to be inlined there.

Since env_get_char() is being changed to simple access to an array, we
can drop the failing cases and simplify the code (this could have been
done before, since env_get_char() did not fail even before).

As usb_ether driver has no compatible string, it can't be find by
lists_bind_fdt(). In bind_by_node_path(), which called lists_bind_fdt(),
the driver entry is known, pass it to lists_bind_fdt() to force the driver

121a165c51 Remove including timestamp.h in version.h
Header file version.h does not use anything from timestamp.h. Including of
timestamp.h has side effect which cause recompiling object file at every
make run because timestamp.h changes at every run.

So remove timestamp.h from version.h and include timestamp.h in files
which needs it.

This change reduce recompilation time of final U-Boot binary when U-Boot
source files were not changed as less source files needs to be recompiled.

bc21ccbaaa version: Remove global macro U_BOOT_VERSION_STRING from version.h
Version string is available in global variable char version_string[].
Macro U_BOOT_VERSION_STRING is not used by any other file, so remove it
completely from version.h. Other files were already converted to use
variable version_string[].

bdfb6d70bb version: Move version_string[] from version.h to version_string.h
More C files do not use compile time timestamp macros and do not have to be
recompiled every time when SOURCE_DATE_EPOCH changes.

This patch moves version_string[] from version.h to version_string.h and
updates other C files which only needs version_string[] string to include
version_string.h instead of version.h. After applying this patch these
files are not recompiled every time when SOURCE_DATE_EPOCH changes.
