ee9c3adc85 board_f: m68k: Factor out m68k-specific bdinfo setup
Factor out m68k-specific bdinfo setup to arch_setup_bdinfo in
arch/m68k/lib/bdinfo.c. Also, use if(IS_ENABLED()) instead of #ifdef where
possible.

Move sram related bdinfo from arch-specific setup_board_part1 to generic

a4aa188948 board_f: Factor out bdinfo bi_mem{start, size} to setup_bdinfo
Move all assignments to gd->bd->bi_mem{start,size} to generic code in
setup_bdinfo.

Xtensa architecture is special in this regard as it defines its own
handling of gd->bd->bi_mem{start,size} fields. In order to avoid defining
a weak SDRAM function, let arch_setup_bdinfo overwrite the generic flags.

For ARC architecture, remove ARCH_EARLY_INIT_R from Kconfig since it is
not needed anymore.

Also, use gd->ram_base to populate bi_memstart to avoid an ifdef.

81e7cb1e71 board_f: Introduce arch_setup_bdinfo initcall
Certain architectures (ppc, mips, sh, m68k) use setup board_part1 and
setup_board_part2 calls during pre-relocation init to populate gd->bd
boardinfo fields. This makes the generic init sequence cluttered with
arch-specific ifdefs.

In order to clean these arch-specific sequences from generic init,
introduce arch_setup_bdinfo weak initcall so that everyone can define their
own bdinfo setup routines.

DRAM bank   = 0x0000000000000002
-> start    = 0x0000000080600000
-> size     = 0x0000000000200000
memstart    = 0x0000000000000000
memsize     = 0x00000000
flashstart  = 0x0000000000000000
flashsize   = 0x0000000000000000
flashoffset = 0x0000000000000000

All other numbers are printed with the number of digits needed for the type
ulong. So use this value as minimum number of digits (precision) for
printing physical addresses.

aaa91a4e4b fit_image: Use calloc() to fix reproducibility issue
Vagrant Cascadian reported that mx6cuboxi target no longer builds
reproducibility on Debian.

One example of builds mismatches:

00096680: 696e 6700 736f 756e 642d 6461 6900 6465  ing.sound-dai.de
-00096690: 7465 6374 2d67 7069 6f73 0000            tect-gpios..
+00096690: 7465 6374 2d67 7069 6f73 0061            tect-gpios.a

This problem happens because all the buffers in fit_image.c are
allocated via malloc(), which does not zero out the allocated buffer.

Using calloc() fixes this unpredictable behaviour as it guarantees
that the allocated buffer are zero initialized.

cc6b87ecaa net: tftp: Add client support for RFC 7440
Add support for RFC 7440: "TFTP Windowsize Option".

This optional feature allows the client and server
to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific
network topology, underlying NIC.
You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

5b3ddb17ba fs/fat/fat.c: Do not perform zero block reads if there are no blocks left
While using u-boot with qemu's virtio driver I stumbled across a
problem reading files less than sector size.  On the real hardware the
block reader seems ok with reading zero blocks, and while we could fix
the virtio host side of qemu to deal with a zero block read instead of
crashing, the u-boot fat driver should not be doing zero block reads
in the first place.  If you ask hardware to read zero blocks you are
just going to get zero data.  There may also be other hardware that
responds similarly to the virtio interface so this is worth fixing.

Without the patch I get the following and have to restart qemu because
it dies.
---------------------------------
=> fatls virtio 0:1
       30   cmdline.txt
=> fatload virtio 0:1 ${loadaddr} cmdline.txt
qemu-system-aarch64: virtio: zero sized buffers are not allowed
---------------------------------

With the patch I get the expected results.
---------------------------------
=> fatls virtio 0:1
       30   cmdline.txt
=> fatload virtio 0:1 ${loadaddr} cmdline.txt
30 bytes read in 11 ms (2 KiB/s)
=> md.b ${loadaddr} 0x1E
