Sparsemem on ep93xx

[Marco Stornelli <marco.stornelli@xxxxxxxxxx>]

Hi all,

I'm using the kernel 2.6.27.7 and the board ts-7200 based on a ep9302
processor. With 64MB of sdram there are some problems because there are
two banks of 32MB with two different chip select, the situation is:

0x00000000
0x01000000
0x04000000
0x05000000
0xe0000000
0xe1000000
0xe4000000
0xe5000000

so the kernel should use 64MB of memory as 8 sections of 8MB. Now the
questions is: how can use the sparsemem with situation? Someone can help
me? Reading the code I guess I have to add the sparsemem support in the
kconfig and I have to modify the memory.h under my mach and add:

#define NODE_MEM_SIZE_BITS 23 // 8mb

Is it sufficient? Any helps are welcome. Thanks.

Regards,

Marco
