2012-12-13env: Use getenv_yesno() more generallyJoe Hershberger
Move the getenv_yesno() to env_common.c and change most checks for 'y' or 'n' to use this helper. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
2012-12-11Add strcasecmp() and strncasecmp()Simon Glass
strncasecmp() is present as strnicmp() but disabled. Make it available and define strcasecmp() also. There is a only a small performance penalty to having strcasecmp() call strncasecmp(), so do this instead of a standalone function, to save code space. Update the prototype in arch-specific headers as needed to avoid warnings. Signed-off-by: Simon Glass <sjg@chromium.org>
2012-12-05mpc5200: Add SPL supportStefan Roese
This patch adds SPL booting support (NOR flash) for the MPC5200 platforms. Signed-off-by: Stefan Roese <sr@denx.de>
2012-12-05SPL: Port SPL framework to powerpcStefan Roese
This patch enables the SPL framework to be used on powerpc platforms and not only ARM. timer_init() does not exist on PPC systems. The timer (decrementer) is initialized and enabled in interrupt_init() here. And currently interrupt_init() is called after relocation to SDRAM. Since the only powerpc SPL implementation (a3m071) doesn't need a timer, let's remove this timer_init() call for PPC systems. Signed-off-by: Stefan Roese <sr@denx.de>

2012-11-27powerpc/p4080ds: fix PCI-e x8 link training down failureYuanquan Chen
Due to SerDes configuration error, if we set the PCI-e controller link width as x8 in RCW and add a narrower width(such as x4, x2 or x1) PCI-e device to PCI-e slot, it fails to train down to the PCI-e device's link width. According to p4080ds errata PCIe-A003, we reset the PCI-e controller link width to x4 in u-boot. Then it can train down to x2 or x1 width to make the PCI-e link between RC and EP.

2012-11-27powerpc/85xx: implement check for erratum A-004580 work-aroundTimur Tabi
The work-around for erratum A-004580 ("Internal tracking loop can falsely lock causing unrecoverable bit errors") is implemented via the PBI (pre-boot initialization code, typically attached to the RCW binary). This is because the work-around is easier to implement in PBI than in U-Boot itself. It is still useful, however, for the 'errata' command to tell us whether the work-around has been applied. For A-004580, we can do this by verifying that the values in the specific registers that the work-around says to update. This change requires access to the SerDes lane sub-structure in serdes_corenet_t, so we make it a named struct.

2012-11-27powerpc/mpc85xx: Temporary fix for spin table backward compatibilityYork Sun
Once u-boot sets the spin table to cache-enabled memory, old kernel which uses cache-inhibit mapping without coherence will not work properly. We use this temporary fix until kernel has updated its spin table code. For now this fix is activated by default. To disable this fix for new kernel, set environmental variable "spin_table_compat=no". After kernel has updated spin table code, this default shall be changed.

The work-around for erratum A-004849 ("CoreNet fabric (CCF) can exhibit a deadlock under certain traffic patterns causing the system to hang") is implemented via the PBI (pre-boot initialization code, typically attached to the RCW binary). This is because the work-around is easier to implement in PBI than in U-Boot itself. It is still useful, however, for the 'errata' command to tell us whether the work-around has been applied.

2012-11-27powerpc/85xx/p5040: add CONFIG_SYS_PPC64, del CONFIG_SYS_FSL_ELBC_MULTIBIT_ECCTimur Tabi
The P5040 has an e5500 core, so CONFIG_SYS_PPC64 should be defined in config_mpc85xx.h. This macro was absent in the initial P5040 patch because it crossed paths with the patch that introduced the macro. Also delete CONFIG_SYS_FSL_ELBC_MULTIBIT_ECC, since it's not used in the upstream U-Boot. It's a holdover from the SDK.

2012-11-278xxx: Change all 8*xx_DDR addresses to 8xxxAndy Fleming
There were a number of shared files that were using CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and several variants (DDR2, DDR3). A recent patchset added 85xx-specific ones to code which was used by 86xx systems. After reviewing places where these constants were used, and noting that the type definitions of the pointers assigned to point to those addresses were the same, the cleanest approach to fixing this problem was to unify the namespace for the 85xx, 83xx, and 86xx DDR address definitions. This patch does: s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g All 85xx, 86xx, and 83xx have been built with this change.

2012-11-26spl/85xx: new SPL supportScott Wood
Update CONFIG_RAMBOOT and CONFIG_NAND_SPL references to accept CONFIG_SPL and CONFIG_SPL_BUILD, respectively. CONFIG_NAND_SPL can be removed once the last mpc85xx nand_spl target is gone. CONFIG_RAMBOOT will need to remain for other use cases, but it doesn't seem right to overload it for meaning SPL as well as nand_spl does. Even if it's somewhat appropriate for the main u-boot, the SPL itself isn't (necessarily) ramboot, and we don't have separate configs for SPL and main u-boot. It was also inconsistent, as other platforms such as mpc83xx didn't use CONFIG_RAMBOOT in this way. Signed-off-by: Scott Wood <scottwood@freescale.com> Cc: Andy Fleming <afleming@freescale.com>

2012-11-26powerpc/mpc85xx: fix TLB alignmentScott Wood
In the RAMBOOT/SPL case we were creating a TLB entry starting at CONFIG_SYS_MONITOR_BASE, and just hoping that the base was properly aligned for the TLB entry size. This turned out to not be the case with NAND SPL because the main U-Boot starts at an offset into the image in order to skip the SPL itself. Fix the TLB entry to always start at a proper alignment. We still assume that CONFIG_SYS_MONITOR_BASE doesn't start immediately before a large-page boundary thus requiring multiple TLB entries.

2012-11-20usb: use linux/usb/ch9.h instead of usbdescriptors.hIlya Yanok
Linux usb/ch9.h seems to have all the same information (and more) as usbdescriptors.h so use the former instead of the later one. As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead. Old usbdescriptors.h included is not removed as it seems to be used by old USB device code. This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).

And this macro has been included by all the corenet architecture platform boards. But in fact, it's uncertain whether all corenet platform boards support this feature. So it may be better to get rid of the macro "CONFIG_FSL_CORENET", and add a special macro for every board which can support the feature.

2012-10-22powerpc/mpc8xxx: Fix DDR SPD failed messageYork Sun
Since empty DIMM slot is allowed on other than the first slot, remove the error message if SPD is not found in this case. Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com>
2012-10-22powerpc/mpc8xxx: Add auto select bank interleaving modeYork Sun
Based on populated DIMMs, automatically select from cs0_cs1_cs2_cs3 or cs0_cs1 interleaving, or non-interleaving if not available. Fix the message of interleaving disabled if controller interleaving is enabled but DIMMs don't support it.

2012-10-22powerpc/mpc85xx: Add workaround for DDR erratum A004934York Sun
After DDR controller is enabled, it performs a calibration for the transmit data vs DQS paths. During this calibration, the DDR controller may make an inaccurate calculation, resulting in a non-optimal tap point.

2012-10-22powerpc/mpc85xx: software workaround for DDR erratum A-004468York Sun
Boot space translation utilizes the pre-translation address to select the DDR controller target. However, the post-translation address will be presented to the selected DDR controller. It is possible that the pre- translation address selects one DDR controller but the post-translation address exists in a different DDR controller when using certain DDR controller interleaving modes. The device may fail to boot under these circumstances. Note that a DDR MSE error will not be detected since DDR controller bounds registers are programmed to be the same when configured for DDR controller interleaving.
