In sdrc_init in board-beagle.c both
writel(0x1A, SDRC_REG(SYSCONFIG));
and
writel(0x18, SDRC_REG(SYSCONFIG));
sets bits 4:3 in the IDLEMODE field. The OMAP3 TRM (spruf98k) defines
0x2 as the only valid value for this field, all others being marked as
"reserved - do not use". board-omap3evm.c does the same thing,
board-sdp343x.c does not.
Anyone knows where these settings come from? Derived from an older
version of the TRM? (I'm thinking there may have been a feature that
was discovered to be unreliable or not working as intended so it was
removed from the docs.)
Thanks,
Orjan
