The board_early_init_f() inits clock before initing pinmux. However,
the clock configuration code might need to adjust PMIC settings of a
PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C
bus pin muxing is not configured before attempting to communicate
with the PMIC, the communication will silently fail and the prcm_init()
may configure fast enough CPU clock that the default voltage provided
by the PMIC would be insufficient and the platform would become
unstable.

The name CONFIG_LEGACY_IMAGE_FORMAT reads slightly better along with
allowing us to avoid a rather nasty Kbuild/Kconfig issue down the line
with CONFIG_IS_ENABLED(IMAGE_FORMAT_LEGACY). In a few places outside of

Overload the weak function board_boot_order() so that besides choosing
the main boot device, we can fallback on USB boot by returning in the
BootROM, eg. if the NOR flash is empty while it was the primary boot
medium.

Implement the weak board_return_to_bootrom() function so that when
enabling the spl_bootrom.c driver, one can make use of usbboot on
spear platforms. All necessary information to return to the BootROM
are stored in the BootROM's stack. The SPL stack pointer is reset so
we save the BootROM's stack pointer into the SPL .data section.

Quoting ARM "RealView Compilation Tools Assembler Guide v4.0":
PUSH and POP are synonyms for STMDB and LDM (or LDMIA), with
the base register sp (r13), and the adjusted address written
back to the base register.
PUSH and POP are the preferred mnemonic in these cases.
Let's follow this recommandation to ease the reading and substitute

First set of u-boot-atmel features and fixes for 2019.10 cycle
This includes the Atmel QSPI driver and support for the at91 boards.
This is the port of the driver from Linux, mostly done by Tudor Ambarus.
Fix the following:
- use "jedec,spi-nor" binding, we use jedec compatible flashes
- set bus width to 4, we use quad capable flashes
- differentiate bewteen data and clk and cs pins
- drop partions as we don't use them in u-boot.

The MPU region dedicated for SDRAM for STM32F4 SoCs family
was set to 16MB, but STM32F429 Evaluation board have 32MB of SDRAM.
When kernel starts, only first 16MB of SDRAM are configured with XN
