Florian Fainelli 210dce5faf ARM: ep93xx: properly wait for UART FIFO to be empty ... 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.
