This inhibits the re-inititialization of DDR during an RTC-only resume. If
this is not done, an L3 NOC error is produced as the DDR gets accessed
before the re-init has time to complete. Tested on AM437x GP EVM.

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.
This is not to be used with epos evm builds.

Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP
with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x
55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header
pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more.
https://beagleboard.org/pocket
This was tested using the am335x_evm_usbspl_defconfig.
Note that MII pins are enabled despite not having Ethernet on this
board. This avoids an issue where otherwise many timeout errors would be
generated. See https://e2e.ti.com/support/arm/sitara_arm/f/791/t/298976

Latest versions of u-boot have increased in size and require more
than the 256kb allocated to it.
The MCR3000 board is equipped with an AM29LV160DB boot flash which
is organised as follows:
- One 16kb block
- Two 8kb block
- One 32kb block
- Thirty one 64kb blocks
At the time being, u-boot is a single piece occupying the 256 first
kbytes, then the environment is stored in the following 64kb block
The environment being quite tiny, we save one 64kb block by embedding
the environment in the first 8kb block, hence allowing to increase
the monitor size to 320kb.

Commit 7653942b10 ("common/env_embedded.c: drop support for
CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was
used in linking scripts to allow fine placement of embedded
environment sections.
This implies that GCC randomly places objects from env/embedded.o
and environment is not guaranteed to be located at the correct address:
04003df8 g F .text 00000038 mii_init
04004000 g O .text 00000004 env_size
04004004 g O .text 00002000 environment
04006004 g F .text 00000040 .hidden __lshrdi3
This patch restores this capability by allocating each object marked
with __UBOOT_ENV_SECTION__ into a different section. Hence
'environment' will be alone in .text.environment, allowing a
fine placement in u-boot.lds with:
. = DEFINED(env_offset) ? env_offset : .;
env/embedded.o (.text.environment)
