9 Say Y here if you are using the Sharp KEV7A400 development
10 board. This hardware is discontinued, so I'd be very
11 surprised if you wanted this option.
14 bool "LPD7A400 Card Engine"
17 # select HAS_TOUCHSCREEN_ADS7843_LH7
19 Say Y here if you are using Logic Product Development's
20 LPD7A400 CardEngine. For the time being, the LPD7A400 and
21 LPD7A404 options are mutually exclusive.
24 bool "LPD7A404 Card Engine"
27 # select HAS_TOUCHSCREEN_ADC_LH7
29 Say Y here if you are using Logic Product Development's
30 LPD7A404 CardEngine. For the time being, the LPD7A400 and
31 LPD7A404 options are mutually exclusive.
39 config LPD7A40X_CPLD_SSP
42 config LH7A40X_CONTIGMEM
43 bool "Disable NUMA/SparseMEM Support"
45 Say Y here if your bootloader sets the SROMLL bit(s) in
46 the SDRAM controller, organizing memory as a contiguous
47 array. This option will disable sparse memory support
48 and force the kernel to manage all memory in one node.
50 Setting this option incorrectly may prevent the kernel
51 from booting. It is OK to leave it N.
53 For more information, consult
54 <file:Documentation/arm/Sharp-LH/SDRAM>.
56 config LH7A40X_ONE_BANK_PER_NODE
57 bool "Optimize NUMA Node Tables for Size"
58 depends on !LH7A40X_CONTIGMEM
60 Say Y here to produce compact memory node tables. By
61 default pairs of adjacent physical RAM banks are managed
62 together in a single node, incurring some wasted overhead
63 in the node tables, however also maintaining compatibility
64 with systems where physical memory is truly contiguous.
66 Setting this option incorrectly may prevent the kernel from
67 booting. It is OK to leave it N.
