From 51928df64ce29ca4c412fe5f3e063cb05e5411c7 Mon Sep 17 00:00:00 2001 From: Liu Gang Date: Thu, 9 Aug 2012 05:09:58 +0000 Subject: powerpc/corenet_ds: Update README.srio-boot-corenet Update some descriptions due to the implementation changes: For master: Get rid of the SRIOBOOT_MASTER build target, and to support for serving as a SRIO boot master via environment variable. For slave: 1. When compile the slave image for boot from SRIO, no longer need to specify which SRIO port it will boot from. 2. All slave's cores should be in hold off.
