This converts the following to Kconfig: CONFIG_SKIP_LOWLEVEL_INIT CONFIG_SKIP_LOWLEVEL_INIT_ONLY In order to do this, we need to introduce SPL and TPL variants of these options so that we can clearly disable these options only in SPL in some cases, and both instances in other cases.

--------
|
|
The LS1021ATWR is a Freescale reference board that hosts the LS1021A SoC.
|
|
|
|
LS1021A SoC Overview
|
|
------------------
|
|
The QorIQ LS1 family, which includes the LS1021A communications processor,
|
|
is built on Layerscape architecture, the industry's first software-aware,
|
|
core-agnostic networking architecture to offer unprecedented efficiency
|
|
and scale.
|
|
|
|
A member of the value-performance tier, the QorIQ LS1021A processor provides
|
|
extensive integration and power efficiency for fanless, small form factor
|
|
enterprise networking applications. Incorporating dual ARM Cortex-A7 cores
|
|
running up to 1.0 GHz, the LS1021A processor delivers pre-silicon CoreMark
|
|
performance of over 6,000, as well as virtualization support, advanced
|
|
security features and the broadest array of high-speed interconnects and
|
|
optimized peripheral features ever offered in a sub-3 W processor.
|
|
|
|
The QorIQ LS1021A processor features an integrated LCD controller,
|
|
CAN controller for implementing industrial protocols, DDR3L/4 running
|
|
up to 1600 MHz, integrated security engine and QUICC Engine, and ECC
|
|
protection on both L1 and L2 caches. The LS1021A processor is pin- and
|
|
software-compatible with the QorIQ LS1020A and LS1022A processors.
