| * socfpga: Allow setting partition xloader boots from for mmcTrent Piepho2015-12-142-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The xloader boots the 2nd stage barebox from socfpga_barebox_part when using NOR. But when using MMC it boots from a hardcoded "disk0.1". Add the mmc device name to the partition description and use it for mmc booting. Add an extern declaration of socfpga_barebox_part to the socfpga header so that a board can change it to use a different partition. Initialize socfpga_barebox_part to the default value instead of NULL to avoid the NULL check later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * | arm: Add RAMOOPS memory areaMarkus Pargmann2015-12-102-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RAMOOPS is a driver that uses a reserved static memory region to store the data from the last panic or boot. This helps to debug crashes at the next boot while preserving the boot messages. To guarantee a memory area that is not altered by barebox or the kernel, this area is located at the end of the RAM right after barebox and before the STACK. This ensures that changing barebox sizes do not interfere with RAMOOPS. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memory calculations used are all hardcoded into three different files, start-pbl.c, uncompress.c and start.c. To make this more readable and reliable, this patch gathers these information in barebox-arm.h with static inline functions for the calculation of the memory offsets. This patch also adds proper handling of different barebox/board data sizes. Currently only 1MB+Alignment of RAM is reserved for Barebox and board data. This could be too small for bigger devicetrees and barebox. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hardware ECC does not work for erased pages. However as soon as something that is not 0xff is found in the page, hardware ECC assumes this is valid data and produces an uncorrectable error ECC status. We can use that to check for bitflips in erased pages and fix them if the number of flipped bits is below the ecc_strength. We need to move the memcpy above the for loop to be able to access the buffer directly. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

The problem can be easily reproduced on a i.MX6 based board with PCIe slot populated with some device by doing: > bootm -f -e 0x1050 <your board's>.img Ignoring this exception seem to allow PCIe core to successfully initialize and enumerate devices properly. This is also how Linux Kernel version of the driver handles this situation -- it installs dummy no-op abort handler at the beginning of device's probing.
