From: Andrew Bradford Date: Thu, 25 Oct 2012 12:21:32 +0000 (-0400) Subject: am335x_evm: Enable use of UART{1,2,3,4,5} X-Git-Tag: v2013.01-rc2~146^2~3^2~8 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c3f8318f33eb4eb79b3b5c5204a438d499572de0;p=oweals%2Fu-boot.git am335x_evm: Enable use of UART{1,2,3,4,5} Add targets of am335x_evm_uart{1,2,3,4,5} to have serial input/output on UART{1,2,3,4,5} for use with the Beaglebone RS232 cape, am335x_evm daughterboard, and other custom configurations. Modify target for am335x_evm to include SERIAL1 and CONS_INDEX=1 options in order to clarify UART selection requirements.
