I can build 'qemu' target with default config, but I can't see any output in emulator. I can't even build 'malta' target with default config. Is it runnable at all? I think, that Shinya's concepts can be used in the future, but they are very complex for initial mips support. IMHO, the Shinya's code is redundant (> 200K ) --- initial support must be as small as possible. The file Kconfig is overcomplicated. Many variables are really unused: DMA_NONCOHERENT, SWAP_IO_SPACE HW_HAS_PCI SYS_SUPPORTS_{32,64}BIT_KERNEL SYS_SUPPORTS_ARBIT_HZ and others In other hand the options ARCH_TEXT_BASE and CPU_BIG_ENDIAN are useful just now, but I have missed them. But now I see, that I can make my mips support better --- split big patch and make some parts of code configurable. -- Best regards, Antony Pavlov _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
