* fdt: Allow ft_board_setup() to report failureSimon Glass2014-11-21-2/+6
| | | | | | | | | | | | | | | | | | This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

* MAINTAINERS: comment out blank M: fieldMasahiro Yamada2014-09-24-1/+1
| | | | | | | | | | | | | | | | | | Since commit ddaf5c8f3030050fcd356a1e49e3ee8f8f52c6d4 (patman: RunPipe() should not pipe stdout/stderr unless asked), Patman spits lots of "Invalid MAINTAINERS address: '-'" error messages for patches with global changes. It takes too long for Patman to process them. Anyway, "M: -" does not carry any important information. Rather, it is just like a place holder in case of assigning a new board maintainer.

* powerpc/T4240QDS/eth: some fix for XFIShaohui Xie2014-08-20-18/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XFI is supported on T4QDS-XFI board, which removed slot3, and four LANEs of serdes2 are routed to a SFP+ cages, which to house fiber cable or direct attach cable(copper), the copper cable is used to emulate the 10GBASE-KR scenario. So, for XFI usage, there are two scenarios, one will use fiber cable, another will use copper cable. For fiber cable, there is NO PHY, while for copper cable, we need to use internal PHY which exist in Serdes to do auto-negotiation and link training, which implemented in kernel. We use hwconfig to define cable type for XFI, and fixup dtb based on the cable type. For copper cable, set below env in hwconfig: fsl_10gkr_copper:<10g_mac_name> the <10g_mac_name> can be fm1_10g1, fm1_10g2, fm2_10g1, fm2_10g2. The four <10g_mac_name>s do not have to be coexist in hwconfig. For XFI ports, if a given 10G port will use the copper cable for 10GBASE-KR, set the <10g_mac_name> of the port in hwconfig, otherwise, fiber cable will be assumed to be used for the port. For ex. if four XFI ports will both use copper cable, the hwconfig should contain: fsl_10gkr_copper:fm1_10g1,fm1_10g2,fm2_10g1,fm2_10g2 For fiber cable: 1. give PHY address to a XFI port, otherwise, the XFI ports will not be available in U-boot, there is no PHY physically for XFI when using fiber cable, this is just to make U-boot happy and we can use the XFI ports in U-boot. 2. fixup dtb to use fixed-link in case of fiber cable which has no PHY. Kernel requests that a MAC must have a PHY or fixed-link. When using XFI protocol, the MAC 9/10 on FM1 should init as 10G interface. Change serdes 2 protocol 56 to 55 which has same feature as 56 since 56 is not valid any longer. Signed-off-by: Shaohui Xie <Shaohui.Xie@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+26
| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/.

* powerpc/t4qds: Add alternate serdes protocols to align with A-007186Shaohui Xie2014-06-05-2/+49
| | | | | | | | | | | | | | | | | A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to increase and cause the PLL to unlock when the temperature delta from the time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V (or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC VCO. Only the protocols using Ring VCOs are impacted. Workaround: For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need to use alternate serdes protocols. The alternate option has the same functionality as the original option; the only difference being LC VCO rather than Ring VCO.
