Subject: Blackfin: bf533-ezkit: convert to physmap/jedec_probe
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7036c61fe043af6b701e10d6426ec22259bd1e3b;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Blackfin: bf533-ezkit: convert to physmap/jedec_probe

Now that the common jedec_probe supports the ST PSD4256G6V, no need to
use the custom stm_flash driver.
