Porting Preloader generation to U-Boot 2016 - FAT Support

Hello all, 

 

I am porting the altera preloader generation to new U-boot and I would need little help. 

 

I am successfully building spl from U-boot configured for my board via QTS Files. 

 

Problem is the FAT Support in this SPL. 

 

When I enable the CONFIG_SPL_FAT_SUPPORT. 

the single SPL File size is increased to ~258 000 bytes. (original is ~55 000 bytes) 

 

my question here: 

Is is possible to make this size same as in Altera U-boot 2013 when generated U-boot and preloader via bsp-editor? 

 

I notice that in altera U-boot there is also some lowlevel confing when using the CONFIG_SPL_FAT_SUPPORT. 

 

/* relocated the stack to SDRAM which is much bigger */ 

relocate_stack_to_sdram(); 

under arch/arm/cpu/armv7/socfpga/lowlevel_init.S 

 

 

is these something similar in u-boot 2016 to enable fat support for spl and reach the required size? 

 

 

Thank you for any advice. 

 

BR,
