linkcmds.base @ f33d3b4

Last change on this file since f33d3b4 was f33d3b4, checked in by Joel Sherrill <joel@…>, on 12/20/17 at 17:36:13

gen5200, gen83xx, gen83x, mpc55xxevb, psim, qoriq, t32mppc, tqm8xx, virtex: Simplify bsp_specs

These BSPs all use shared/startup/linkcmds.base and thus needed to be
modified at the same time. Variations in the arguments were reflected
into the BSP specific portions of the linkcmds.

Updates #3520.
