After setting, I could access DM9000 with the Base address 0xD0000000.
In here, I have some more questions.
1. I set the 1 TLB entry, so others does not affect the address
translation.
so Whenever I use the 0xD0000000, it always converted to 0xD 0000
0000
on the bootloader.
Am I right?
Yes, looks good.
2. On the linux, If I want to use ioremap for Dm9000, Do I need to set
the TLB
and do not need to change the ioremap source code ?
Make sure you have CONFIG_64BIT_PHYS_ADDR configured
and you are using a recent kernel. No changes to any code and ioremap()
will ensure the TLB is set correctly. Just use the virtual address
returned from ioremap().
