Seriously, did you really think I would not notice what you're doing
here?
Yes , I know that you have very good understanding about this.
You're reading the previous value which either contains a default
mapping or has the mapping set by the bootloader, and write it back to
the register along with a new mask and the REGEN bit set (which
BTW is wrong since you don't mask out other fields before updating
them).
There is no other field get overwritten
This confirms that this Core -> FPI address translation exists
and has to be set properly, so please stop lying about that.
Sorry, there is no SW translation, as I have mentioned that it's
optional only, for safer side , reading and writing the default values.
The memory region to enabled that's my concern so written the same
register values.
This will not be impact other fields, so please see below for reference
The EBU Address Select Registers EBU_ADDR_SEL_0 to EBU_ADDSEL3 establish
and control memory regions for external accesses.
Reset Value: 17400001H
