Hi,
2013/12/17 Shimoda, Yoshihiro <yoshihiro.shimoda.uh at renesas.com>:
> The SH7753 EVB board has SH7753, 512MB DDR3-SDRAM, SPI ROM,
> Gigabit Ethernet, and eMMC.
>
> This patch support the following functions:
> - 512MB DDR3-SDRAM, SCIF4, SPI ROM, Gigabit Ethernet, eMMC
>
> This patch changes the support for sh7752evb to sh7753evb.

Why do you remove sh7752evb?
Isn't this already use or discontinue? There is no user any longer?
If that is right, you should divide the patch which removes sh7752evb,
and the patch to which sh7753evb is added.
Could you split patches?
Best regards,
Nobuhiro
