943bf78a48 binman: Allow extracting a file in an alternative format
In some cases entries encapsulate other data and it is useful to access
the data within. An example is the fdtmap which consists of a 16-byte
header, followed by a devicetree.

Provide an option to specify an alternative format when extracting files.
In the case of fdtmap, this is 'fdt', which produces an FDT file which can
be viewed with fdtdump.

858436dfda binman: Allow listing an image created by a newer version
If an older version of binman is used to list images created by a newer
one, it is possible that it will contain entry types that are not
supported. At present this produces an error.

Adjust binman to use a plain 'blob' entry type to cope with this, so the
image can at least be listed.

7945077f79 binman: Allow providing tools and blob directories
At present it is necessary to symlink files containing external blobs into
the U-Boot tree in order for binman to find them. This is not very
convenient.

Add two new environment/Makefile variables to help with this. Add
documentation as well, fixing a related nit.

d5b6e91ba2 bloblist: Support allocating the bloblist
Typically the bloblist is positioned at a fixed address in memory until
relocation. This is convenient when it is set up in SPL or before
relocation.

But for EFI we want to set it up only when U-Boot proper is running. Add
a way to allocate it using malloc() and update the documentation to cover
this aspect of bloblist.

Note there are no tests of this feature at present, nor any direct testing
of bloblist_init().

This can be added, e.g. by making this option controllable at runtime.

080f859cf1 binman: Use normal entries in cbfs
This currently uses _cbfs_entries[] to store entries. Since the entries
are in fact valid etypes, we may as well use the same name as
entry_Section uses, which is _entries. This allows reusing more of the

e586f44ea7 binman: Allow control of which entries to read
The ObtainContents() and GetEntryContents() methods in this file read
every single entry in the section. This is the common case.

However when one of the entries has had its data updated (e.g. with
'binman replace') we don't want to read it again from the file. Allow
the entry to be skipped, for this purpose. This is currently done in the
CBFS implementation, so adding it here will allow that to use more of
the entry_Section code.

34bee10e00 sandbox: replace putchar(ch) by fputc(ch, stdout)
When compiled with -Og for better debugability u-boot ends up in a stack
overflow using

    gcc (Ubuntu 11.2.0-7ubuntu2) 11.2.0
    GNU Binutils for Ubuntu 2.37

putchar(ch) is defined as a macro which ends up calling U-Boot's putc()
implementation instead of the glibc one, which calls os_putc() ...

Let's use fputc(ch, stdout) instead as fputc() does not exist in U-Boot.

666da85dc9 board: ae350: Support autoboot from RAM
Add boot command "bootcmd_ram" to support autoboot from RAM.

This feature could be useful at the very initial state of chip design
when there is only a minimal set of peripheral. (e.g. without mmc and mac ..etc)

The kernel image is default to be loaded at 0x2000000 via debug port,
and the following script serves as an example:

spl()
{
	cmd="riscv64-linux-gdb -q \
	-ex \"target remote $host:$port\" \
	-ex \"load\" \
	-ex \"thread apply all set \\\$pc=&_start\" \
	-ex \"thread apply all set \\\$a0=\\\$mhartid\" \
	-ex \"thread apply all set \\\$a1=<dtb address>\" \
	-ex \"restore u-boot.itb binary 0x200000\" \
	-ex \"restore Image binary 0x2000000\" \
	-ex \"c\" \
	spl/u-boot-spl
	"

	echo $cmd
	eval $cmd
}

The address where the kernel is loaded can be altered by
changing the value of KERNEL_IMAGE_ADDR.

8777033722 net: eth-phy: Handle gpio_request_by_name() return value
The gpio_request_by_name() returns zero in case of success, however the
conditional return value check in gpio_request_by_name() checks only for
(ret != -ENOENT) and if the condition is true, returns ret outright.

This leads to a situation where successful gpio_request_by_name() return
leads to immediate successful eth_phy_of_to_plat() return as well, and
to skipped parsing of "reset-assert-us" and "reset-deassert-us", so the
PHY driver operates with valid reset GPIO, but with assert/deassert times
set to default, which is 0, instead of the values from DT. This breaks
PHY reset.

Fix this by checking if return value is non-zero and then for this one
single allowed non-zero return value, -ENOENT.

8c1a6957b1 drivers: net: Soft reset felix switch core
It turns out that in custom designs if the system is reset
multiple times in conjunction with a slight increase in external
temperature, the felix  switch starts to behave in a strange way:
packets are no longer received on the ENECT interface connected
to the L2switch internal port (the TX side of internal port stops working
or the packets do not reach there. It is not very clear where
the packets remain blocked. None of the counters points to a disruption
in the L2switch)
The issue is not reproducible on NXP reference designs.

It was observed that by adding the switch core reset, the problem
goes aways, even if intensive testing in temperature chambers
is applied.

The current patch performs soft reset on the switch core to ensure proper
operation of the L2switch.
