> Since commit 2580a2a7e719 ("mtd: nand: Increase max sizes of OOB and
> Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build
> with the following error message:
>   arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big
>
> They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer
> as static data:
>
>     static uint8_t page_buffer[NAND_MAX_PAGESIZE];
>
> This buffer required 8KB in .bss section before that commit and now
> it has been increased to 16KB.  Given limited code/memory size for SPL,
> it is not a good idea to allocate a page buffer statically.  In the
> first place, the load address 'dst' can be used as a page buffer.
