[U-Boot] SPL binary too large for OMAP4460 OCM

[bin4ry]

Hi everyone,

I changed CONFIG_SPL_TEXT_BASE from 0x40300300 to 0x40300350 and
sufddenly it works. Do you know why this configuration works, even
though with this configuration there are 0x50 bytes less?
It even works with a MLO with 47519 bytes.

Here the summary of my config:

/* Defines for SPL */
#define CONFIG_SPL
#define CONFIG_SPL_TEXT_BASE            0x40300350
#define CONFIG_SPL_MAX_SIZE             (46 * 1024)
#define CONFIG_SPL_STACK                LOW_LEVEL_SRAM_STACK


Thanks again for the support!
-b
