[ Upstream commit a7b484b1c9332a1ee12e8799d62a11ee3f8e0801 ]
Since we're using these two macros to read a value from a register, we need to use the FIELD_GET instead of the FIELD_PREP macro, otherwise we're getting wrong values.
So instead of:
[ 3.111779] ocmem fdd00000.sram: 2 ports, 1 regions, 512 macros, not interleaved
we now get the correct value of:
[ 3.129672] ocmem fdd00000.sram: 2 ports, 1 regions, 2 macros, not interleaved
