7398c1b758 mtd: spi-nor-core: Don't check for zero length in spi_nor_write() / spi_nor_erase()
This check is already done in all callers: mtdcore's mtd_write() /
mtd_erase(), legacy spi_nor_write() / spi_flash_erase(). No reason to do
this here as well.

a67b3719f3 mtd: spi-flash: Check for zero length in legacy spi_flash_*()
Check for zero length in the legacy spi_flash_read() /
spi_flash_write() / spi_flash_erase() functions.
On zero length, return 0 immediately, don't call the underlying method.

Rationale:
- these legacy functions call the _read(), _write() and _erase() methods
  of struct mtd
- the DM callers of these methods already check for zero length
- making all callers of these methods check for zero length makes it
  possible to remove the check from implementations of these _read(),
  _write() and _erase() methods

e66c6f1027 mtd: spi-nor: Add support for Spansion S25FL256L
The S25FL256L is a part of the S25FL-L family and has the same feature set
as S25FL128L except the density.

The datasheet can be found in the following link.
https://www.cypress.com/file/316171/download

The S25FL256L is 32MB NOR Flash that does not support Bank Address
Register. This fixup is activated if CONFIG_SPI_FLASH_BAR is enabled and
returns ENOTSUPP in setup() hook to avoid further ops.

Tested on Xilinx Zynq-7000 FPGA board.

  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).

53f5d1688e firmware: zynqmp: fix write to an uninitialised pointer in ipi_req()
When a caller is not interested in the returned message, the ret_payload
pointer is set to NULL in the u-boot-sources. In this case, under EL3, the
memory from address 0x0 would be overwritten by ipi_req() with the returned
IPI message, damaging the original data under this address. The patch, in
case ret_payload is NULL, assigns the pointer to the array holding the IPI
message being sent.

eafdcda4a8 net: gem: Disable broadcast setting
There is no need for GEM to accepts broadcast packets because they are not
handled by u-boot anyway. That's why use HW IP feature and don't waste time
on these packats which will be dropped anyway.

398a74ae33 zynqmp: restore the jtag interface
When boot.bin is configured for secure boot the CSU will disable the
JTAG interface on all cases.

Some boards might rely on this interface for flashing to QSPI in which
case those systems might end up bricked during development.

This commit will restore the interface under CSU control
