For some platforms such as Qualcomm we need to wait for the UART to be ready before writing characters to the UART in the same manner as the macro in debug.S used with the main "Uncompressing Linux ..." text. Pass an extra temporary variable to writeb and make it call waituarttxrdy and busyuart just like the other decomression messages. Optionally it will also call waituartcts if and only if CONFIG_DEBUG_UART_FLOW_CONTROL is selected. After this the decompression debug messages work fine on Qualcomm platforms if you compile head.S with -DDEBUG.
