* Merge branch 'for-next/pstore'Sascha Hauer2016-01-114-0/+289

| * fs: Add pstore filesystemMarkus Pargmann2015-12-102-0/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pstore is a persistent storage filesystem used for RAMOOPS. It is used to store console logs, panics, ftrace and other information in case of a crash/panic/oops/reboot. pstore is implemented for barebox as a read-only filesystem at the moment. It may be extended later on. The idea is to provide a way to extract essential data from the last running kernel. Most of the code is copied from the kernel. However this is only a lightweight implementation without real write support yet. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | mtd: nand: Add erased page bitflip check helper functionsMarkus Pargmann2016-01-041-0/+5
| |/ | | | | | | | | | | | | | | | | | | This adds the bitflip check helper functions from the kernel. They are used to check for bitflips in erased pages and correct them in the buffer so that UBI can work with it. Unfortunately most nand controllers do not have ECC for erased pages and don't do this on their own.

* / linux/barebox-wrapper: Silence gcc5 warningSascha Hauer2015-12-101-2/+2
|/ | | | | | | | | | | gcc5 warns about using flags uninitialized in spin_lock_irqsave, although it could look into the static inline spin_lock_irqsave implementation and see it's not used at all. An empty define instead of the static inline wrapper would lead to a "unused variable" warning. Let's create a macro and fake some usage of the flags variable. This probably helps until gcc6 is out.

| | | | | | | | | | | | | | | | | | If a device has the reset-gpios property we can support this through the reset controller API, so drivers do not have to open code the support for this property each time themselves as done a few dozen times in the kernel.

* | fbconsole: register fonts dynamicallySascha Hauer2015-11-131-4/+3
|/ | | | | | | | | | | | | | | Instead of having a fixed array of fonts register the fonts dynamically. This allows easier adding of fonts to the tree since only one file per font has to be added and no other files modified. Currently we have to register the fonts very early before the first framebuffer is registered. This is because of our limited dev_add_param_enum() which wants to know the number of elements when called, so we can't add elements once after we've called dev_add_param_enum(). Maybe a dev_add_param_array() has to be created whithout this limitation, but that's left for a future exercise. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on commit 3d6f4a20cc287a8980c6186624834cf10a70752b Author: David Miller <davem@davemloft.net> Date: Thu Jul 24 23:38:31 2008 -0700 endian: Always evaluate arguments. In barebox.git/drivers/usb/core/usb.c, function usb_parse_config() we have had le16_to_cpus(&(dev->config.wTotalLength)); which evaluates to "do { } while (0)" on little endian, so struct usb_configuration field misuse will never be discovered on little endian.

| | | | | | | | | | Some SPI NOR flashes support 4K erase blocks. 4K erase blocks do not work with UBIFS which needs a minimum erase block size of 15360 bytes. Also bigger sectors are faster to erase. This patch adds a device tree option to use the bigger blocks instead of the default 4K blocks.

E.g. see 'git grep -A 4 of_device_id drivers/' output: drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = { drivers/ata/sata-imx.c- { drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci", drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6, drivers/ata/sata-imx.c- }, { Here is of_device_id struct in linux kernel v4.0: struct of_device_id { char name[32]; char type[32]; char compatible[128]; const void *data; }; Changing of_device_id.data type to 'const void *data' will increase barebox' linux kernel compatibility and decrease number of 'unsigned long' casts.
