Bootrom loads SPL from SDCARD or eMMC
according BootPin selection.
Then SPL loads U-Boot on the same mmc device
with the following predefined GPT partitioning:
on SDCARD: gpt partitioning
1: SPL
2: SPL#2
3: U-Boot
4: bootable partition
on eMMC:
The 2 boot partitions are used for SPL (2 copy)
boot1: SPL
boot2: SPL#2
The user partition use gpt partitioning
1: U-Boot
2: bootable partition
This patch select the correct SPL partition
(3 for SDCARD on mmc0 and 1 for eMMC on mmc1)
according the BootRom information saved in TAMP register
and based on configuration flasg:
- CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION
=> for BOOT_DEVICE_MMC1 or mmc 0 in U-Boot
- CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_MMC2 (new)
=> for BOOT_DEVICE_MMC2 or mmc 1 in U-Boot
And the correct boot_targets is selected according the environment

to search the bootable partition with kernel on this device

Kernel stores information to the RTC_SCRATCH0 and RTC_SCRATCH1 registers
for wakeup from RTC-only mode with DDR in self-refresh. Parse these
registers during SPL boot and jump to the kernel resume vector if the
device is waking up from RTC-only modewith DDR in Self-refresh.
The RTC scratch register layout used is:
SCRATCH0 : bits00-31 : kernel resume address
SCRATCH1 : bits00-15 : RTC magic value used to detect valid config
SCRATCH1 : bits16-31 : board type information populated by bootloader
During the normal boot path the SCRATCH1 : bits16-31 are updated with
the eeprom read board type data. In the rtc_only boot path the rtc
scratchpad register is read and the board type is determined and
correspondingly ddr dpll parameters are set. This is done so as to avoid
costly i2c read to eeprom.
RTC-only +DRR in self-refresh mode support is currently only enabled for
am43xx_evm_rtconly_config.

Patch queue for rpi - 2018-04-06
Highlights this time around:
- Support for new RPi3 B+ model
- Fix for some SD cards on newer RPi firmware
In raspberrypi-firmware 7fdcd00e00a42a1c91e8bd6f5eb8352fe9358557 and
later start.elf now sets the EMMC clock to 200 MHz.
According to Phil Elwell in
https://github.com/raspberrypi/firmware/issues/953
the SDHost controller shares the core/VPU clock and doesn't use
the EMMC clock.
Use the core clock id when determining the frequency to allow
U-Boot to work with recent versions of raspberrypi-firmware.

More ARC changes and fixes for v2018.05
* Update of ARC tools to the most recent arc-2017.09
* Fix for compile-time warning for AXS10x
* Add support of platform-specific commands for HSDK
* Add support for on-board SPI flash on HSDK
Note though that for write support another series [1]
is required. I hope that Jagan will be able to review and
act on SPI flash improvement series before we get beyond RC1.
Also note that to get clean build for HSDK we need to disable
stack-usage check [2] as our current GCC erroneously tries to calculate
stack-usage on a naked function which leads to warning.
