* kbuild: rename SRCTREE to srctreeMasahiro Yamada2014-03-12-1/+1
| | | | | | | | | | | | | | | Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for pointing to the top of source directory. (No difference between the two.) In Kbuild style, $(srctree) is used for instead. This commit renames SRCTREE to srctree and deletes the defition of SRCTREE. Note that SRCTREE in scripts/kernel-doc, scripts/docproc.c, doc/DocBook/Makefile should be keep. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* kbuild: change out-of-tree buildMasahiro Yamada2014-02-19-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the working directory where the build process occurs. Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>
* cam_enc_4xx: Move CONFIG_SPL_PAD_TO to a config headerMasahiro Yamada2013-09-06-2/+0
| | | | | | | | | | | | | | | | | | | | For most boards which define CONFIG_SPL_PAD_TO, it is defined in config header files. Currently, there exists only one exception, cam_enc_4xx board. This patch moves CONFIG_SPL_PAD_TO definition from board/ait/cam_enc_4xx/config.mk to include/configs/cam_enc_4xx.h. With this modification, we can delete a glue code in the top level config.mk: ifneq ($(CONFIG_SPL_PAD_TO),) CPPFLAGS += -DCONFIG_SPL_PAD_TO=$(CONFIG_SPL_PAD_TO) endif Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Cc: Heiko Schocher <hs@denx.de>
* spl: Change PAD_TO to CONFIG_SPL_PAD_TOScott Wood2012-12-19-1/+1
| | | | | | | | | | | | This was already used by some SPL targets, and allows the pad amount to be specified by board config headers rather than only in makefile fragments. Also supply a pad-to of zero if the variable is undefined. It works without this, but this avoids relying on undocumented behavior.

* ARM: davinci: fixes for cam_enc_4xx boardHeiko Schocher2012-03-27-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - change CONFIG_ENV_RANGE to contain 2 nand erase blocks, one for bad block reserve. - remove from the envvariable "img_writeramdisk" the ubifsmount command, as it is not needed. - erase the hole mtd partition containing u-boot - save environment variable "dvn_app_vers" and "dvn_boot_vers" only after installing the new image. changes requested from Marek Vasut: - arm, davinci: fix eldk-4.2 warnings for cam_enc_4xx board - get rid of run_command2 usage needed since patch: commit 009dde1955583e306cf904c864068f3acb0db499 Author: Simon Glass <sjg@chromium.org> Date: Tue Feb 14 19:59:20 2012 +0000 Rename run_command2() to run_command() is now in mainline. - add CONFIG_SPL_LIBGENERIC_SUPPORT support - remove CONFIG_CMD_PXE support - fix warning: cam_enc_4xx.c: In function 'menu_handle': cam_enc_4xx.c:609: warning: dereferencing type-punned pointer will break strict-aliasing rules - fix error: arm-linux-ld: u-boot-spl: Not enough room for program headers, try linking with -N Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Marek Vasut <marex@denx.de> Cc: Tom Rini <tom.rini@gmail.com> Cc: Fletzer Martin <Martin.Fletzer@ait.ac.at> Cc: Wolfgang Denk <wd@denx.de>

- DM368 SOC - booting with spl not with UBL from TI - before loading u-boot from NAND into RAM, test the RAM with the post memory test. If error is found, switch all LEDs on and halt system. - SPI Flash Dataflash Typ: M25PE80 - Ethernet DM9161BI - MMC - USB Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Sandeep Paulraj <s-paulraj@ti.com> Cc: Albert ARIBAUD <albert.u.boot@aribaud.net> Cc: Igor Grinberg <grinberg@compulab.co.il> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
