From 4e4b7952cd34af4dd78e012265d4bc858db6adf3 Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Wed, 27 Jul 2005 11:46:01 -0700 Subject: [PATCH] [PATCH] cpm_uart: use DPRAM for early console m8xx_cpm_hostalloc() can't rely on using the coherent DMA allocator early on boot because the VM is not fully up yet. Change it to use the on-board DPRAM instead. The current code relies on the "bootmem_page" allocated by m8xx_cpm_reset(), which must be killed. This is done in v2.4 but has never been forward ported to v2.6.
