[PATCH v2 00/12] Puma RK3399 migration to TPL and numerous fixes

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at theobroma-systems.com>

Puma RK3399 SoM struggled for a few releases already to boot because the
SPL was too big. Therefore, let's migrate to TPL like most RK3399-boards
already did a few releases ago.

This also fixes numerous issues around fallback booting (U-Boot proper
corrupted on the storage medium from where TPL/SPL was loaded) and default
order of boot targets.

It also forces the environment storage medium to be the same as the one
from which U-Boot proper was loaded, for a more consistent user
experience.

The environment can also be stored on SPI flash now.

Finally some cleanup and the migration of the flashing instructions to
u-boot-rockchip.bin and u-boot-rockchip-spi.bin.

A small patch for Lion RK3368 also, for migrating the flashing
instructions to u-boot-rockchip.bin.

Cheers,
Quentin

v2:
 - rebase on top of latest master,
 - removed dependency on patch removing SPL_PAD_TO by moving the
 "custom" SPL payload offset to puma/lion u-boot dtsi,
