| * libfile: Error out if out of memory in read_file_2()Andrey Smirnov2018-10-161-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All other error cases in read_file_2() are handled gracefully, so there shouldn't be any reason not do so for the case of trying to allocate too much memory. This error path can be easily triggered with: barebox_update file-bigger-than-availible-ram.img Currently this would result in a crash which is not really desirable from user experience.

* | kfifo: roundup fifo size to next power of twoSascha Hauer2018-09-211-0/+10
|/ | | | | | | | | | | Comments in include/kfifo.h state that the FIFO size will be rounded up to the next power of two, but so far we haven't actually done this, probably because we didn't have roundup_pow_of_two() back then when kfifo support was added. Fix that now and do what the comments state. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* libfile: open_and_lseek: don't imply O_RDONLYUwe Kleine-König2018-08-101-1/+1
| | | | | | | | | | There are several users that pass O_RDWR or O_WRONLY in mode to open_and_lseek() and use the resulting file descriptor for writing. This is no real issue becauce O_RDONLY is 0 and so can be dropped without any side effects.

* cmdlinepart: Allow empty stringSascha Hauer2018-07-091-0/+3
| | | | | | | | | | | | Currently when cmdlinepart_do_parse() is called with an empty partitions string then an unnamed partition with size 0 is created. This is wrong of course and instead no partition should be created. With this barebox no longer crashes while booting when all partitions are deleted on the commandline using "nand0.partitions=" Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* | ARM: lib64: Make string functions aware of MMU configurationAndrey Smirnov2018-06-111-6/+12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Optimized version of memset() in memset.S if called as: memset(foo, 0, size) will try to explicitly zero out data cache with: dc zva, dst which will result in Alignement Exception (DABT) if MMU is not enabled. For more info see: - C4.4.8 "DC ZVA, Data Cache Zero by VA" - D5.2.8 "The effects of disabling a stage of address translation" in "ARM Architecture Reference Manual. ARMv8, for ARMv8-A architecture profile" In similar vein, using optimized version of memcpy() could lead to a unaligned 16-byte write (using 'stp'), which is not allowed for Device-nGnRnE type of memory (see D5.2.8) and would liead to Alignement Exception. To fix both problems expose non-optimized and optimzied versions of the function and created a wrapper to dispatch the call to either one based on if MMU is enabled or not.

* console: Introduce console_drain()Andrey Smirnov2018-04-171-25/+5
| | | | | | | | | | | | | | Generalize high baud rate UART polling code found in lib/xmodem.c and expose it as a generic function in console API. The usecase for this -- besides X/Y-mode data transfers where the code originated -- is command/reply type of serial exchages at high baud rates (~1Mbaud) with payloads exceeding inernal UART FIFOs in size. Such interactions are not uncommon in serdev device and this patch is done in preparation for serdev support code that will follow.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to the nature of TFTP which can't lseek and due to the silliness of our filesystem implementation which can't cache accesses we have to manually cache files on TFTP filesystems sometimes. Make it easier for them by providing a cache_file() function which copies the file from TFTP to RAM. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Since we do not have any concurrency in barebox we do not need to create the file right away and can leave that to the caller. Unlike unix mktemp the resulting filename is dynamically allocated and must be freed by the caller. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
