[PATCH u-boot-marvell v3 00/39] kwboot higher baudrate

[Marek Behún]

From: Marek Behún <marek.behun at nic.cz>

Hello Stefan and others,

here's v3 of series adding support for booting Marvell platforms via
UART (those bootable with kwboot) at higher baudrates.

Tested on Turris Omnia up to 5.15 MBd, which is 44x faster than
115200 Bd.

The user can direct kwboot to use higher baudrate via the -B option.
(BTW this option was there before but did not work with the -b option.)

Only the payload part of the KWB image is uploaded at this higher
baudrate. The header part is still uploaded at 115200 Bd, since the code
that changes baudrate is injected into header as a binary extension.
(The payload part makes up majority of the binary, though. On Turris
 Omnia the payload currently makes ~87%.)

The series also contains various other fixes, refactors and improvements
of the code, upon which the main change is done.

Marek & Pali

Changes since v2:
- fixed integer overflow in patch 15
- fixed commit title in patch 32

Changes since v1:
- fixed uploading of older kwb images, now all kwb images should be able
  to upload at faster baudrate
- fixed injecting code that changes baudrate back
- various other fixes and refactors, the best way to compare with v1 is
  to apply v1 and v2 separately and compare the resulting kwboot.c
