From: Petr Hodina <[email protected]>
Upstream Linux explicitly disables ufs_mem_hc/ufs_mem_phy for all Tama
devices (sdm845-sony-xperia-tama.dtsi):
/* BIG WARNING! DO NOT TOUCH UFS, YOUR DEVICE WILL DIE! */
&ufs_mem_hc { status = "disabled"; };
&ufs_mem_phy { status = "disabled"; };
PURGE/UNMAP command issued to these devices' UFS erases the bootloader
and permanently bricks the device.
