| | | | | | | | | | | Linux kernel can enumerate mmc sd as either mmcblk0 or mmcblk1. But u-boot default environment assumes that sd always populates as mmcblk0.

* fat: handle paths that include ../Stephen Warren2015-09-11-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FAT code contains a special case to parse the root directory. This is needed since the root directory location/layout on disk is special cased for FAT12/16. In particular, the location and size of the FAT12/16 root directory is hard-coded and contiguous, whereas all FAT12/16 non-root directories, and all FAT32 directories, are stored in a non-contiguous fashion, with the layout represented by a linked-list of clusters in the FAT. If a file path contains ../ (for example /extlinux/../bcm2835-rpi-cm.dtb), it is possible to need to parse the root directory for the first element in the path (requiring application of the special case), then a sub- directory (in the general way), then re-parse the root directory (again requiring the special case). However, the current code in U-Boot only applies the special case for the very first path element, and never for any later path element. When reparsing the root directory without applying the special case, any file in a sector (or cluster?) other than the first sector/cluster of the root directory will not be found. This change modifies the non-root-dir-parsing loop of do_fat_read_at() to detect if it's walked back to the root directory, and if so, jumps back to the special case code that handles parsing of the root directory. This change was tested using sandbox by executing: ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/.." ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup/" ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup/.." ./u-boot -c "host bind 0 ../sd-p1.bin; ls host 0:0 /extlinux/../backup/../" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /extlinux/../bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /backup/../bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /extlinux/..backup/../bcm2835-rpi-cm.dtb" ./u-boot -c "host bind 0 ../sd-p1.bin; load host 0:0 0 /extlinux/../backup/../bcm2835-rpi-cm.dtb" (/extlinux and /backup are in different sectors so trigger some different cases, and bcm2835-rpi-cm.dtb is in a sector of the root directory other than the first). In all honesty, this change is a bit of a hack, using goto and all. However, as demonstrated above it appears to work well in practice, is quite minimal, likely doesn't introduce any risk of regressions, and hopefully doesn't introduce any maintenance issues. The correct fix would be to collapse the root and non-root loops in do_fat_read_at() and get_dentfromdir() into a single loop that has a small special-case when moving from one sector to the next, to handle the layout difference of root/non-root directories. AFAIK all other aspects of directory parsing are identical. However, that's a much larger change which needs significantly more thought before it's implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commits adds a generic support for q8 formfactor a13 based tablets. These tablets ship in many variants, with the difference mainly being the touchscreen controller / accelerometer / wifi chip used. The wifi is USB based, and thus not listed in devicetree. ATM the kernel does not support the touchscreen / accelerometer on these devices. In the future we may need multiple configs with different CONFIG_DEFAULT_DEVICE_TREE settings, this depends on how we solve the hw differences on the kernel side. For now this will suffice. The dts files are identical to the dts files submitted to the upstream kernel for these tablets. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

Looking at the surrounding code, I found the same problem in all other composite gadget drivers in both the bind and unbind functions, as well as the udc platform driver 'remove' functions. Those will break if anyone uses the 'unbind' sysfs attribute to detach a device from a built-in driver. This patch removes the incorrect annotations from all the gadget drivers.

* | x86: quark: Avoid chicken and egg problemBin Meng2015-09-09-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we convert to use driver model pci on quark, we will encounter some chicken and egg problems like below: - To enable PCIe root ports, we need program some registers on the message bus via pci bus. With driver model, the first time to access pci bus, the pci enumeration process will be triggered. But without first enabling PCIe root ports, pci enumeration just hangs when scanning PCIe root ports. - Similar situation happens when trying to access GPIO from the PCIe enabling codes, as GPIO requires its block base address to be assigned via a pci configuration register in the bridge. To avoid such dilemma, replace all pci calls in the quark codes to use the local version which does not go through driver model.
