This is unfortunate as for some platforms (sama5d3 and earlier), it ends up in the PCI zone and PCI is enabled in multi_v7. Switch to DEBUG_UART_VIRT to solve that. Tested on sama5d3 and 9g20.

ARM: at91: avoid defining CONFIG_* symbols in source code 2016-03-02T16:31:08+00:00 Arnd Bergmann arnd@arndb.de 2016-02-23T14:39:38+00:00 e91fb3bd757569aca48785358a4adbf41334d382 In an invalid randconfig build (fixed by another patch), I ran across this warning: arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror] #define CONFIG_DEBUG_UART_VIRT AT91_IO_P2V(CONFIG_DEBUG_UART_PHYS) As Russell pointed out, we should never #define a macro starting with CONFIG_ in a source file, as that is rather confusing.

In an invalid randconfig build (fixed by another patch),
I ran across this warning:

arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror]
 #define CONFIG_DEBUG_UART_VIRT AT91_IO_P2V(CONFIG_DEBUG_UART_PHYS)

As Russell pointed out, we should never #define a macro starting
with CONFIG_ in a source file, as that is rather confusing.

This renames the macro to avoid the symbol clash.
