radeon gart table size

[Jerome Glisse]

Hi,

I believe gart table size should scale with gart size. With current
value of table size 32*1024 we can have a gart size of at most
(((32*1024/4)*4096)/1024)/1024) = (32*4096)/(4*1024)=32Mo

This is in drm radeon_cp.c firstopen table_size. Is a fix where
we compute table size from the gart size would be ok ? Or is
there old reasons for this to being set like it's now.

Cheers,
Jerome Glisse
