That makes sense since this is an improvement and not a bug fix.

My last PR was rejected (at least, discouraged) due to the number of
changes and release is approaching. But I will not try to pick up random
patches from u-boot-imx master and try to push it just to get it in
release. I am starting to pick up all pacthes that are ready in -next,
starting from u-boot-imx, -master.

Regards,
Stefano

Stefano,

Any chance this can be adopted?  I have a bunch of patches pending
this, because my SPL is tight and this patch gives it some breathing
room.

[U-Boot] [PATCH v2] ARM: imx: Support larger SPL size on IMX6DQ

2019-08-08 Thread Robert Hancock
Previously the SPL size on all iMX6 platforms was restricted to 68KB
because the OCRAM size on iMX6SL/DL parts is only 128KB. However, the
other iMX6 variants have 256KB of OCRAM. Add an option
CONFIG_MX6_OCRAM_256KB which allows using the full size on boards which
don't need to support the SL/DL variants. This allows for an SPL size of
196KB, which makes it much easier to use configurations such as SPL with
driver model and FDT control.

Signed-off-by: Robert Hancock

Changed since v2: Remove "default n" in Kconfig since that is the default.
