2014-07-18	1ed827a Browse files » ARM: i.MX: esdctl: i.MX53 has esdctl v4, not v3 ... On the i.MX53 this has the effect that in early init only half of the memory bank is detected and the barebox image is place in the middle of SDRAM.

If we have two discontinuous memory banks we want to move the malloc area into the upper bank by default to leave as much free space in the lower bank, where we have to place kernel, oftree and initrd.

As this is a pretty invasive change, use the opportunity to make the signature 64bit safe.

2013-03-26	f1e1dc3 Browse files » ARM i.MX ESDCTL: Fix default enabled esdctl v2 controller ... On some i.MX SoCs the SDRAM controller has chipselect 2 enabled by reset default. This confuses our SDRAM size detection. We already have a fix for this in place. This patch adds the fix for i.MX35 which needs it aswell. Also since we now detect the SDRAM size in the SoC specific entry functions we have to apply the fixup there, too.

2012-12-12	11cb162 Browse files » esdctl: fix reset default bug on i.MX27/31 ... The i.MX27/31 have the second chip select enabled by reset default. This can be considered as a hardware bug, because even boards which need this settings cannot work out of reset because of the missing initialization sequence. Detect this reset default setting and disable this chipselect then to be able to properly detect the SDRAM size.

To reduce the risk of registering wrong SDRAM sizes this patch adds a driver for the ESDCTL which reads back the configured SDRAM size and registers the memory found with barebox.
