[U-Boot] [PATCH 0/3] OMAP: Detect reset type and handle sdram init after warm rese

[Lokesh Vutla]

Certain modules are not affected by means of a warm reset and need not 
be configured again. Adding an API to detect a warm reset. 

Emif is one such module that need not be configured after warm reset.
All the registers are retained.So, skipping DDR init after warm reset.
Freq_update is done to make sure timing registers are configured for
appropriate frequency.
This is tested on omap4430 sdp.
Boot tested on omap5430uevm and omap5432sevm.

Patch 3 is taking care of Errata:i727

Lokesh Vutla (3):
  ARM: OMAP3+: Detect reset type
  OMAP4+: Handle sdram init after warm reset
  OMAP4+: Force DDR in self-refresh after warm reset
