2012-12-12ARM: ep93xx: properly wait for UART FIFO to be emptyFlorian Fainelli1-7/+3
This patch changes the busy-waiting loop around in the decompressor putc() function on the UART FIFO register. Without a proper wait, the output of the decompressor was corrupted like this: Uncompressing Linx. done, booting th enl To highlight the issue more evidently, looping 100 times instead of 1000 makes the issue appear much faster. This patch takes the approach of using an active while loop until the FIFO is empty (not FULL). This issue happened to me on Sim.One running at 200Mhz.

2008-10-03[ARM] 5276/1: ep93xx: allow selecting UART for early kernel messagesHartley Sweeten1-6/+15
Currently on the EP93xx platform early kernel messages go to UART1. Since this UART is the only one that has modem control signals it might be used for another purpose and it is undesirable for those messages to appear. This patch allows one of the other UARTs to be selected in the kernel configuration. It is assumed that the bootloader has configured and initialized the UART since this was the previous assumption.
