Kumar,
is it possible to change TLB alloc way?
current u-boot TLB is easy to conflict/confus to users.
there are two limitations
1) the magic number 8 for DDR
2) the TLB14/TLB15 never can be used to board code.
These are TLBs that board code can use just like
0,1....7,skip DDR(8....), skip 14 and 15.
Basically it is limited to 0-7.
