From 24956642ef7de5d8340683d721113f993ffaa0a8 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 15 Sep 2010 09:33:25 +0200 Subject: Remove unused CONFIG_SERIAL_SOFTWARE_FIFO feature This patch removes the completely unused CONFIG_SERIAL_SOFTWARE_FIFO feature from U-Boot. It has only been implemented for PPC4xx and was not used at all. So let's remove it and make the code smaller and cleaner.

Snyder" Date: Fri, 10 Sep 2010 15:42:32 -0700 Subject: e300: increase CONFIG_SYS_BOOTMAPSZ to allow booting large kernels Newer Linux kernels can overrun the initial memory window used for booting with their BSS area. When this happens, they overwrite the FDT and silently fail to boot. On e300 CPUs, the Linux kernel uses an initial BAT covering the first 256MB of RAM. See arch/powerpc/kernel/head_32.S for details. Increase the value of CONFIG_SYS_BOOTMAPSZ to accommodate the maximum value allowed by Linux. This will allow very large kernels to boot. Signed-off-by: Ira W.
