Subject: zynq: lmb: do not add to lmb map before relocation
X-Git-Url: http://git.dujemihanovic.xyz/html/static/%7B%7B%20%24.Site.BaseURL%20%7D%7Dposts/index.xml?a=commitdiff_plain;h=cef34baad10c27cb089c4ab2c61689513467ab82;p=u-boot.git

zynq: lmb: do not add to lmb map before relocation

The LMB memory is typically not needed very early in the platform's
boot. Do not add memory to the LMB map before relocation. Reservation
of common areas and adding of memory is done after relocation.
