Authored by Vaibhav Hiremath

Exists in v3.2_SMARCT335xPSP_04.06.00.11 and in 3 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN

ARM: OMAP2: AM33XX: id: Add support for new AM335x PG2.1 Si 

Add support for chip id detection of AM335x PG2.1 Silicon.

Currently omap3xxx_check_revision() detects PG1.0 and PG2.0,
so this patch extends it by adding PG2.1 Si support.
