Re: [U-Boot] [PATCH] mx23: Put back RAM voltage level to its original value

Dear Fabio Estevam,

From: Fabio Estevam fabio.estevam@freescale.com

commit 5c2f444c9 (mxs: Reset the EMI block on mx23) changed the DDR voltage level, which causes mx23evk to fail to load a kernel.

Put back the original values, so that mx23evk can boot a kernel again.

So, here are the results from M28EVK and MX23EVK:

What you can see (rather what's wrong on MX23): - VDDA should be 1V5, but jumps over 2V and stabilizes at 1V7 - VDDIO has some weird ripple where it goes to 3V5 - VDDMEM is FUBAR
