9 Say Y here if you are using the Sharp KEV7A400 development
10 board. This hardware is discontinued, so I'd be very
11 suprised if you wanted this option.
14 bool "LPD7A400 Card Engine"
18 Say Y here if you are using Logic Product Development's
19 LPD7A400 CardEngine. For the time being, the LPD7A400 and
20 LPD7A404 options are mutually exclusive.
23 bool "LPD7A404 Card Engine"
27 Say Y here if you are using Logic Product Development's
28 LPD7A404 CardEngine. For the time being, the LPD7A400 and
29 LPD7A404 options are mutually exclusive.
37 config LH7A40X_CONTIGMEM
38 bool "Disable NUMA Support"
39 depends on ARCH_LH7A40X
41 Say Y here if your bootloader sets the SROMLL bit(s) in
42 the SDRAM controller, organizing memory as a contiguous
43 array. This option will disable CONFIG_DISCONTIGMEM and
44 force the kernel to manage all memory in one node.
46 Setting this option incorrectly may prevent the kernel from
47 booting. It is OK to leave it N.
49 For more information, consult
50 <file:Documentation/arm/Sharp-LH/SDRAM>.
52 config LH7A40X_ONE_BANK_PER_NODE
53 bool "Optimize NUMA Node Tables for Size"
54 depends on ARCH_LH7A40X && !LH7A40X_CONTIGMEM
56 Say Y here to produce compact memory node tables. By
57 default pairs of adjacent physical RAM banks are managed
58 together in a single node, incurring some wasted overhead
59 in the node tables, however also maintaining compatibility
60 with systems where physical memory is truly contiguous.
62 Setting this option incorrectly may prevent the kernel from
63 booting. It is OK to leave it N.
