| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The upcoming v1.5.1 version of libfdt adds a dependency on the C99 INT32_MAX symbol. This is ok for use in the host tool, but libfdt can also be embedded into barebox, where it would fail as we don't define this anywhere. Fix this by providing an appropriate definition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The semantic of reset_source_set_instance() required a separate call to reset_source_set() (or reset_source_set_priority()) and checked right usage only using the type. Make the set of functions a bit easier to use by dropping reset_source_set_instance() and instead introduce a function that can set all relevant parameters (source, priority and instance) in one go.

| * | | mtd: nand: gpmc: Add BCH16 supportSascha Hauer2019-08-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for BCH16 ECC encoding. The support is mostly taken from Linux-5.3-rc6. One major change is the different wrap mode used. The Kernel uses wrapmode 1, which means "pass all data through the BCH engine". Still the Kernel has to skip the OOB marker which is done by reading all user data, then use NAND_CMD_RNDOUT to position right behind the OOB marker and then read the ECC data. Instead of doing this we use wrap mode 4 which allows us to bypass the OOB marker from the BCH engine automatically. This explains bch_wrapmode = 1, eccsize0 = 0, eccsize1 = 52 vs. bch_wrapmode = 4, eccsize0 = 4, eccsize1 = 52 Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | | elf: add 64 bits elf loading supportClement Leger2019-09-061-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add elf64 loading support to the elf loader. Since elf32 and elf64 uses completely different types, to avoid copying all the code and simply replace elf32 with elf64, use a macro which will return the appropriate field for each type of header. This macro generates getter for elf structures according to the class of the loaded elf. All direct elf struct dereference are then replaced by call to generated functions. This allows to keep a common loader code even if types are different.

Fix this by amending (struct cdev)::puts with a new nbytes parameter, which is correctly propagated. All this functions now return at most the nbytes parameter they were passed in. This fixes __console_puts, which used to count new lines twice in its return value.
