[U-Boot] [PATCH] gpio: dwapb_gpio: Add reset ctrl to driver
by Ley Foon Tan 04 Sep '18

04 Sep '18

Add code to reset all reset signals as in gpio DT node. A reset property is an optional feature, so only print out a warning and do not fail if a reset property is not present. If a reset property is discovered, then use it to deassert, thus bringing the IP out of reset.

[U-Boot] [PATCH 1/3] PCI: dm: Ignore 64-bit memory regions if CONFIG_SYS_PCI_64BIT not set
by Tuomas Tynkkynen 04 Sep '18

04 Sep '18

Currently, qemu_arm_defconfig and qemu_arm64_defconfig only work with the 'highmem=off' parameter passed to QEMU's virt machine. The reason is that when 'highmem' is not disabled, QEMU appends 64-bit a memory resource to the PCI controller's regions property in DT in addition to the 32-bit PCI memory window in low memory. And the current DT parsing code picks the last (thus the 64-bit one) memory resource, whose address eventually gets silently truncated to 32 bits because CONFIG_SYS_PCI_64BIT is not set, which obviously causes PCI to break. Avoid this problem by ignoring memory regions whose addresses are above the 32-bit boundary when CONFIG_SYS_PCI_64BIT is not set.

[U-Boot] [PATCH v6 00/31] SPI-NAND support
by Miquel Raynal 03 Sep '18

03 Sep '18

During the last months, Boris Brezillon shared his work to support serial flashes within Linux. First, he delivered (and merged) a new layer called spi-mem. He also initiated in Linux MTD subsystem the move of all 'raw' NAND related code to a raw/ subdirectory, adding at the same time a NAND core that would be shared with all NAND devices. Then, he contributed a generic SPI-NAND driver, making use of this NAND core, as well as some vendor code to drive a few chips. On top of this work, I made some cleanups in the MTD layer and added an 'mtd' U-Boot command to handle all sort of MTD devices. This should become the default command instead of having one per flash flavor ('sf', 'nand', 'spi-nand' ?). The series has been tested on an Ocelot board PCB123 (VSC7514), featuring a Macronix SPI NAND chip. TL;DR: the series contains: - A few patches from Linux to resynchronize some areas of the MTD layer. - Various fixes and re-organization of the MTD subsystem. - The introduction of the SPI-mem interface. - The addition of the generic SPI-NAND driver (and its bindings). - Several SPI NAND chip drivers (Macronix, Micron, Winbond). - A new 'mtd' command. - Support for spi-nand devices in mtdparts. To test your SPI-NAND device with U-Boot simply follow these lines: > setenv mtdparts mtdparts=spi-nand0:1m(foo),-(bar) > ubi part bar # create a static UBI volume in the bar partition > mtd list # show the current MTD devices/partitions Thanks, Miquèl Changes since v6: ----------------- * Squashed Boris' fixes about build issues in Travis. * Merged Stefan Roese's contributions. * cmd: mtdparts: * added fallthrough comments in switch blocks deriving sizes. * balanced debug messages to compare freed and allocated partitions. * move mtdparts_init() declaration in mtd/partitions.h to be used in mtd command as well. * introduced a "compatibility" function to return what the MTD device name could be thanks to the mtdids environment variable (which is useless with the new partitioning logic). * mtd: mtdpart: * reworked the way partitions are created/handled. * cmd: mtd: * implement a partitioning logic that takes the best out of the MTD layer without re-inventing the wheel. Partitions are all freed correctly when the value of mtdparts changes. * balance get_mtd_device() by put_mtd_device() calls. * prevent memory leak by reorganizing the code a bit in do_mtd. * do not reconstruct partition list when a partition is already in use (complain about that instead). * add support for the legacy mtdids (not needed anymore if mtdparts directly uses the MTD device names as in Linux. * cmd: ubi: * clean and simplify the partition handling a bit to make use the best use of the MTD layer as well and keep the code simple. Changes since v5: ----------------- * Included Boris fixup about the build issues. * Added Rb/Ab tags from Jagan on patchs 20/21. Changes since v4: ----------------- * Added Jagan's Acked-by tags to every patch related to the SPI-mem/SPI-NAND addition. * Rebased on top of master. Changes since v3: ----------------- * Fixed the debug messages in spi-mem to print either Rx or Tx data. * Fixed a Kconfig error that prevented to build mtdparts with plain defconfig. * Fixed a compilation error due to the above error that prevented one file to be compiled. * Adapted the mtd command to probe MTD partitions also. * Declared mtd_probe_devices() in a header so mtdparts or UBI could use it too (to probe all devices and MTD partitions in a clean way). * As I worked on mtdparts, I found annoying and completely useless the fact that we need to prefix the environment variable with "mtdparts=". Canceled this obligation. * Added one patch to allow spi-nand devices to be recognized by mtdparts (this is purely useless but needed to be done in order to use this command). * Removed useless definitions of MTD device types in UBI code. * Wrote a generic mtdparts environment variable parser, used by the mtd command. * Used the mtd_probe_devices() function from get_mtd_info() in cmd/mtdparts.c to be sure the desired partition really does not exist (otherwise it will be probed and then found). Changes since v2: ----------------- * Rebased on u-boot master branch. * Removed extra-parenthesis in "mtd: Fallback to ->_read/write() when ->_read/write_oob() is missing" * s/fiels/files/ in "mtd: move NAND fiels into a raw/ subdirectory" * Do not describe generic SPI device properties in SPI NAND bindings. * Changes in the mtd command: * Printing more information in 'mtd list' (device type, device characteristics) * Switch to do_div() instead of '(u32)value64b % value32b' which only worked because value32b was a power of 2. * Removed erase.chip option. * By default, erase/read/write happen on the full MTD device while a dump will only work on a single page. Changes since v1: ----------------- * Fixed the nand_memorg structure of the MX35LF2GE4AB chip. * Added Reviewed-by tags from Jagan. * Backported and squashed two patches fixing things in the SPI NAND core received on the Linux ML. * Backported more changes in mtdcore.c from Linux. * Added a patch to add a fallback on mtd->_read/_write() in mtdcore.c when mtd->_read/write_oob() is not supported. * Removed the DT changes, useless as the DTs are not available in mainline yet. * Addressed Boris/Stefan comments on the 'mtd' command. * Added support for multi-pages OOB read/write.

[U-Boot] [PATCH v7 00/13] Cleaner MTD devices management
by Miquel Raynal 03 Sep '18

03 Sep '18

The introduction of the SPI-NAND framework and, more widely, the support of non parallel-NOR, parallel-NAND and SPI-NOR has shown that extending U-Boot MTD devices/partitions handling was not straightforward at all. While this first series [1] is a great step forward, it is not actually usable due to purely software limitations. This series intends to: * Do some cleanup in the MTD layer * Add a new 'mtd' command that should replace in the future all the MTD-specific commands like 'nand' and 'sf'. * Make deep changes in the partition handling by introducing a new way of managing MTD partitions (that soon will be also sent to the Linux kernel), and adding a generic 'mtdparts' environment variable parser in prevision of the 'mtdparts' command removal. * The UBI command is also updated to stop messing with partitions that should just be declared in the 'mtdparts' variable. People can now do the following without 'mtdids': # setenv mtdparts "nor0=1m(some),-(more);spi-nand0=-(all)" Partitions are visible with: # mtd list And UBI support is available with (for the above example): # ubi part all At least these two missing features will be added with further changes: * 'mtd write' on NANDs should use by default the trimffs option (to avoid writing empty pages). * 'nand bad' is a great way to know the list of detected bad-blocks and could be implemented in 'mtd'. Of course, this series only applies on top of [1].

[U-Boot] [PATCH v1] Makefile: Don't generate position independent code
by Andy Shevchenko 03 Sep '18

03 Sep '18

Since gcc-8 the --enabled-default-pie starts producing code which assembler can't translate in case of U-Boot. The build fails with {standard input}: Assembler messages: {standard input}:21100: Error: junk at end of line, first unrecognized character is `@' {standard input}:21120: Error: junk at end of line, first unrecognized character is `@' and so on. This is usually the case for x86 platform because in many cases it uses host compiler from the Linux distributions, where PIE is enabled by default.

[U-Boot] [PATCH] pci: Support parsing PCI controller DT subnodes
by Marek Vasut 03 Sep '18

03 Sep '18

The PCI controller can have DT subnodes describing extra properties of particular PCI devices, ie. a PHY attached to an EHCI controller on a PCI bus. This patch parses those DT subnodes and assigns a node to the PCI device instance, so that the driver can extract details from that node and ie. configure the PHY using the PHY subsystem.

[U-Boot] [PATCH v2 0/8] Device tree support for Powerpc in u-boot
by Jagdish Gediya 01 Sep '18

01 Sep '18

In current implementation, Powerpc does not support device tree in u-boot. This patch enables device tree support for PowerPC platform . T2080AQDS board used as first platform. Dtb is embedded in the u-boot following below steps using binmam tool. 1. Remove bootpg and resetvec section if required 2. Append dtb using binman 3. Append bootpg and resetvec section back if removed in 1st step. To enable binman tool, 'binman' node has been added in the device tree.

[U-Boot] [PATCH v2 00/17][RESENT] efi_loader: EFI_UNICODE_COLLATION_PROTOCOL
by Heinrich Schuchardt 01 Sep '18

01 Sep '18

This patchset implements the EFI_UNICODE_COLLATION_PROTOCOL and provides unit tests. Additionally some errors when handling Unicode strings are fixed. * possible stack overflow * incorrect handling of precision attribute in printf() * incorrect limit on variable length Some old Unicode functions are replaced. An error in Unicode handling in the FAT file system shall be fixed after merging Takahiro's FAT patches. Until then some redundancy between old and new Unicode functions remains. v2: use CONFIG_IS_ENABLED(EFI_LOADER) instead of defined(CONFIG_EFI_LOADER) && !defined(CONFIG_SPL_BUILD) add configuration option EFI_UNICODE_CAPITALIZATION use ut_assert*() for testing test illegal Unicode sequences add more comments Heinrich Schuchardt (17): vsprintf.c: use #if CONFIG_IS_ENABLED(EFI_LOADER) test: print_ut.c use #if CONFIG_IS_ENABLED(EFI_LOADER) lib: build charset.o only if needed efi_loader: rename utf16_strlen, utf16_strnlen lib: charset: utility functions for Unicode test: unit tests for Unicode functions lib: vsprintf: correct printing of Unicode strings test: test printing Unicode efi_loader: remove limit on variable length efi_loader: don't use unlimited stack as buffer efi_loader: buffer size for load options lib: charset: remove obsolete functions efi_loader: capitalization table lib: charset: upper/lower case conversion test: tests for utf_to_lower() utf_to_upper(). efi_loader: EFI_UNICODE_COLLATION_PROTOCOL efi_selftest: EFI_UNICODE_COLLATION_PROTOCOL MAINTAINERS | 4 + cmd/bootefi.c | 6 +- include/capitalization.h | 2028 +++++++++++++++++ include/charset.h | 187 +- include/cp1250.h | 40 + include/cp437.h | 40 + include/efi_api.h | 21 + include/efi_loader.h | 5 + include/test/suites.h | 3 +- lib/Makefile | 5 + lib/charset.c | 359 ++- lib/efi_loader/Kconfig | 10 + lib/efi_loader/Makefile | 18 +- lib/efi_loader/efi_bootmgr.c | 2 +- lib/efi_loader/efi_boottime.c | 6 + lib/efi_loader/efi_console.c | 20 +- lib/efi_loader/efi_file.c | 2 +- lib/efi_loader/efi_unicode_collation.c | 329 +++ lib/efi_loader/efi_variable.c | 52 +- lib/efi_selftest/Makefile | 1 + .../efi_selftest_unicode_collation.c | 260 +++ lib/vsprintf.c | 29 +- test/Kconfig | 8 + test/Makefile | 1 + test/cmd_ut.c | 13 +- test/print_ut.c | 6 +- test/unicode_ut.c | 539 +++++ 27 files changed, 3824 insertions(+), 170 deletions(-) create mode 100644 include/capitalization.h create mode 100644 include/cp1250.h create mode 100644 include/cp437.h create mode 100644 lib/efi_loader/efi_unicode_collation.c create mode 100644 lib/efi_selftest/efi_selftest_unicode_collation.c create mode 100644 test/unicode_ut.c -- 2.18.0
