2014-09-25powerpc: add --bss-plt to LDFLAGSChris Packham
With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected) it is necessary to specify --bss-plt to get the final blrl in the _GOT2_TABLE_. Without this the last symbol does not get it's address relocated. For the P2041RDB board this ended up being NetArpWaitTimerStart which caused the ARP packets to timeout immediately.

2014-09-25driver/ddr: Restruct driver to allow standalone memory spaceYork Sun
U-boot has been initializing DDR for the main memory. The presumption is the memory stays as a big continuous block, either linear or interleaved. This change is to support putting some DDR controllers to separated space without counting into main memory. The standalone memory controller could use different number of DIMM slots.

2014-09-24mpc8xx: move common linker scripts into the CPU directoryMasahiro Yamada
Each CPU of PowerPC has its default linker script under the CPU directory, except mpc8xx. Every mpc8xx board has its own linker script under the board directory, resulting in lots of duplication of linker scripts. I notice eight mpc8xx boards have the same linker script. We can decrease the number of linker scripts by putting a single default linker script, arch/powerpc/cpu/mpc8xx/u-boot.lds.

Fix following issues in USB device-tree fixup: - returns when either dr_mode or phy_type not defined. This was terminating fix-up when only either property was defined in hwconfig string - updates dr_mode_type or dr_phy_type with junk value when their index is -1.

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <[email protected]>
2014-09-08net: Merge asm/fsl_enet.h into fsl_mdio.hClaudiu Manoil
fsl_enet.h defines the mapping of the usual MII management registers, which are included in the MDIO register block common to Freescale ethernet controllers. So it shouldn't depend on the CPU architecture but it should be actually part of the arch independent fsl_mdio.h. To remove the arch dependency, merge the content of asm/fsl_enet.h into fsl_mdio.h. Some files (like fm_eth.h) were simply including fsl_enet.h only for phy.h. These were updated to include phy.h instead. Signed-off-by: Claudiu Manoil <[email protected]>

2014-07-30kconfig: switch to KconfigMasahiro Yamada
This commit enables Kconfig. Going forward, we use Kconfig for the board configuration. mkconfig will never be used. Nor will include/config.mk be generated. Kconfig must be adjusted for U-Boot because our situation is a little more complicated than Linux Kernel. We have to generate multiple boot images (Normal, SPL, TPL) from one source tree. Each image needs its own configuration input. Usage: Run "make <board>_defconfig" to do the board configuration. It will create the .config file and additionally spl/.config, tpl/.config if SPL, TPL is enabled, respectively. You can use "make config", "make menuconfig" etc. to create a new .config or modify the existing one. Use "make spl/config", "make spl/menuconfig" etc. for spl/.config and do likewise for tpl/.config file. The generic syntax of configuration targets for SPL, TPL is: <target_image>/<config_command> Here, <target_image> is either 'spl' or 'tpl' <config_command> is 'config', 'menuconfig', 'xconfig', etc. When the configuration is done, run "make". (Or "make <board>_defconfig all" will do the configuration and build in one time.) For futher information of how Kconfig works in U-Boot, please read the comment block of scripts/multiconfig.py. By the way, there is another item worth remarking here: coexistence of Kconfig and board herder files. Prior to Kconfig, we used C headers to define a set of configs. We expect a very long term to migrate from C headers to Kconfig. Two different infractructure must coexist in the interim. In our former configuration scheme, include/autoconf.mk was generated for use in makefiles. It is still generated under include/, spl/include/, tpl/include/ directory for the Normal, SPL, TPL image, respectively.

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <[email protected]> Acked-by: Marek Vasut <[email protected]> Reviewed-by: Marek Vasut <[email protected]>

This is a workaround for 32 bit hardware limitation of TDM. T1040 has 36 bit physical addressing, TDM DMAC register are 32 bit wide but need to store address of CCSR space which lies beyond 32 bit address range. This workaround creats a LAW to enable access of TDM DMA to CCSR by mapping CCSR to overlap with DDR. A hole of 16M is created in memory using device tree.
