> 
> * Only DT based boards are supported
> * Moving to common-clk breaks things including cpufreq
>   and others. Thomas is working on a patch for this
> * We disable the gpio implementation, which also breaks
>   stuff, but Thomas has a patch already
> * Using the generic DMA engine API in SPI and ASoC
>   means they no longer work on S3C
> * I did not like the solution for the UART driver, but
>   could also not think of a better one.
> * The FB_S3C, S3C2410_WATCHDOG and S3C_ADC drivers
>   are left as an exercise to the reader, they are
>   currently disabled with multiplatform
> * sparsemem support is not available on multiplatform

For booting, you might want to add fixing up of the initcalls
to your checklist too as that can easily cause surprises to
other SoCs.
