2013-08-09nds32: introduce DMA allocation APIken kuo
U-Boot does not compile for the adp-ag101 boards since commit a8f9cd1893bef05b92f63242228607b45821c4a7 (net: update FTGMAC100 for MMU/D-cache support) The driver assumes that the DMA allocation API are provided by all architectures. This is not the case for nds32 and it causes a build error. This patch adds DMA allocation API to avoid the errors.

2013-07-24nds32: introduce macros for bit manipulationGabor Juhos
U-Boot does not compile for the adp-ag101 boards since commit f6c3b34697bf8bf05cb4e81c2fd3cadb9a98daea (mmc: update Faraday FTSDC010 for rw performance) The driver assumes that the bit manipulation macros are provided by all architectures. This is not the case for nds32 and it causes a build error like this: ftsdc010_mci.c: In function 'ftsdc010_clkset': ftsdc010_mci.c:118: warning: implicit declaration of function 'setbits_le32' ftsdc010_mci.c:123: warning: implicit declaration of function 'clrbits_le32' drivers/mmc/libmmc.o: In function `ftsdc010_request': /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:234: undefined reference to `setbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:243: undefined reference to `clrbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:234: undefined reference to `clrbits_le32' drivers/mmc/libmmc.o: In function `ftsdc010_clkset': /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:118: undefined reference to `clrbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:118: undefined reference to `clrbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:121: undefined reference to `setbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:123: undefined reference to `setbits_le32' /devel/u-boot.git/drivers/mmc/ftsdc010_mci.c:123: undefined reference to `setbits_le32' The patch adds bit manipulation macros for the nds32 architecture to avoid the errors. The macros are copied from the ARM implementation. Compile tested only.

2013-05-08nds32: Use sections header to obtain link symbolsKuan-Yu Kuo
Include this header to get access to link symbols, which are otherwise removed. Signed-off-by: Kuan-Yu Kuo <ken.kuoky@gmail.com> Cc: Macpaul Lin <macpaul@gmail.com>
2013-03-15Change stub example to use asm-generic/sections.hSimon Glass
We can use the declarations of __bss_start and _end from this header instead of declaring them locally. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-15Introduce generic link section.h symbol filesSimon Glass
We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
2013-03-15Replace __bss_end__ with __bss_endSimon Glass
Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-18nds32: Add a basic errno.hSimon Glass
This is available on other architectures, and nds32 will start to break without it as code starts to use error numbers more. Signed-off-by: Simon Glass <sjg@chromium.org>

2013-02-01nds32: Drop tlb_addr from global dataSimon Glass
This field doesn't appear to be used for anything important, so drop it. Signed-off-by: Simon Glass <sjg@chromium.org>
2013-02-01Add architecture-specific global dataSimon Glass
We plan to move architecture-specific data into a separate structure so that we can make the rest of it common. As a first step, create struct arch_global_data to hold these fields. Initially it is empty. This patch applies to all archs at once. I can split it if this is really a pain. Signed-off-by: Simon Glass <sjg@chromium.org>
2012-10-19nds32: Change global data baudrate to intSimon Glass
This doesn't need to be a long, so change it. Also adjust bi_baudrate to be unsigned. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Rini <trini@ti.com>
2012-08-11nds32: drop bi_enetaddr from global dataMike Frysinger
Nothing is using this, so punt it from the gd. Seems to just be a copy & paste wart from the initial port. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-08-09global_data: unify global flag definesMike Frysinger
All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-05-15net: punt bd->bi_ip_addrMike Frysinger
This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
