The C6X function call instruction has a limited range of +/- 2MiB.
61
+
This is sufficient for most kernels, but some kernel configurations
62
+
with lots of compiled-in functionality may require a larger range
63
+
for function calls. Use this option to have the compiler generate
64
+
function calls with 32-bit range. This will make the kernel both
65
+
larger and slower.
66
+
67
+
If unsure, say N.

Say Y if you plan on running a kernel in big-endian mode.
101

Note that your board must be properly built and your board
102

port must properly enable any big-endian related features
103

of your chipset/board/processor.

help
109

The kernel memory allocator divides physically contiguous memory
110
+
blocks into "zones", where each zone is a power of two number of
111
+
pages. This option selects the largest power of two that the kernel
112
+
keeps in the memory allocator. If you need to allocate very large
113
+
blocks of physically contiguous memory, then you may need to
114
+
increase this value.
115
+
116
+
This config option is actually maximum order plus one. For example,
117
+
a value of 11 means that the largest free memory block is 2^10 pages.
