1150 Loongson2F have built-in DDR2 and PCIX controller. The PCIX controller
1151 have a similar programming interface with FPGA northbridge used in
1152 Loongson2E.

1234 Please make sure to pick the right CPU type. Linux/MIPS is not
1235 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1236 *not* work on R4000 machines and vice versa. However, since most
1237 of the supported machines have an R4000 (or similar) CPU, R4x00
1238 might be a safe bet. If the resulting kernel does not work,
1239 try to recompile with R3000.

1441 Loongson 2F01 / 2F02 processors have the NOP & JUMP issues which
1442 require workarounds. Without workarounds the system may hang
1443 unexpectedly. For more information please refer to the gas
1444 -mfix-loongson2f-nop and -mfix-loongson2f-jump options.
1445
1446 Loongson 2F03 and later have fixed these issues and no workarounds
1447 are needed. The workarounds have no significant side effect on them
1448 but may decrease the performance of the system so this option should
1449 be disabled unless the kernel is intended to be run on 2F01 or 2F02
1450 systems.
1451
1452 If unsure, please say Y.

1765 The kernel memory allocator divides physically contiguous memory
1766 blocks into "zones", where each zone is a power of two number of
1767 pages. This option selects the largest power of two that the kernel
1768 keeps in the memory allocator. If you need to allocate very large
1769 blocks of physically contiguous memory, then you may need to
1770 increase this value.
1771
1772 This config option is actually maximum order plus one. For example,
1773 a value of 11 means that the largest free memory block is 2^10 pages.
1774
1775 The page size is not necessarily 4KB. Keep this in mind
1776 when choosing a value for this option.
