[U-Boot] [PATCH] arm/pxa: fix and cleanup of pxa_mem_setup macro v2

[Marek Vasut]

> WARNING: This macro do not assume the values for K0DB4, KxDB2, KxFREE,
>          K1RUN, K2RUN and APD bits of CONFIG_SYS_MDREFR_VAL as it was
>          done early on many pxa platforms. All pxa developers that plan
>          to use this macro should check the validity of their MDREFR
> values.
> 
> v1:
>   * strict following to section 6.4.10 of Intel PXA27xx Developer's Manual.
>   * use r7 to store CONFIG_SYS_MDREFR_VAL as r6 is used in pxa_wait_ticks.
> 
> v2:
>   * rename pxa_mem_setup macro to pxa2xx_mem_setup
>   * setting of MDREFR[K1RUN] and MDREFR[K2RUN] bits may be optional
>   * skip certain configuration steps if SDRAM is not present/configured
>   * improve/fix comments

Hi, was there any final conclusion on this one ? It seems it was superseded by 
changes in uboot?
