[LEDE-DEV] [PATCH] brcm47xx: relocate loader to higher address

Hi Hauke,

Currently, BZ_TEXT_START - LOADADDR = 0x80400000 - 0x80001000 = 3FF000 = 4190208 bytes
Today's trunk brcm47xx kernel is 4069124 bytes. So increasing the address is actually
just a preventive countermeasure for future kernels.(?)
The WRT54GL CFEs seem to use a memory area about half the size of your WRT54GS'
So I guess, the actual problem for the WRT54GL was that the stack was smashed?

Once my compiling machine finishes your ar71xx with kernel 4.9, I'll test this one here :-)

Happy to see, that this problem seems to be solved.

Regards,
P. Wassi
