Add a function to relocate the stack from OCRAM to SDRAM.
Hi,
is this functionality really needed ? There's like 128 KiB of OCRAM on SoCFPGA,
On cyclone5 and arria5, there is only 64KiB.
Ooops, sorry, my bad. You're right. But that is still boatload of memory, given that the SPL will use some hundreds of bytes for the stack under normal conditions.
which should be plenty, right? If moving the stack to SDRAM is really needed, then you might want to use the common stack relocation code (see relocate_code() function). Also, you should thoroughly describe the reason in the commit message, in this case it's really important.
I'll update in v2.
So uh, what's the reason for moving the stack into the SDRAM anyway please ?
Best regards, Marek Vasut
