Refer to the commit 70f8c8316ad(PMC: add new mck function to lower rate while switching) from AT91Bootstrap.

While switching to a lower clock source, we must switch the clock source first instead of last. Otherwise, we could end up with too high frequency on internal bus and peripherals. This happen on SAMA5D2 as we exit from ROM code @396MHz.

Add a function pmc_mck_init_down() to allow this sequence.

The SAMA5D27-SiP (System in Package) integrates the SAMA5D2 with 1Gbit DDR2-SDRAM in a single package.

The SAMA5D27 SOM1 embeds a 64Mbit QSPI flash, KSZ8081 Phy and Mac-address EEPROM.

Changes in v3: - Rebase on the PATCH: Atmel PIT timer driver and Remove CONFIG_SYS_EXTRA_OPTIONS. - Use the new Atmel PIT timer driver. - Remove "SAMA5D2" from CONFIG_SYS_EXTRA_OPTIONS options. - Move CONFIG_ENV_IS_IN_FAT to Kconfig.

Changes in v2: - Add the reviewed-by tag. - Add the help in Kconfig to describe the board and peripherals. - Add the code to display the company's logo and board information. - Replace the code to set the ethernet mac address with the common code from the board/atmel/common folder.
