* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting the next AN or SN flag was being done in two different ways throughout the code; e.g. here for AN: ratp_set_an(ratp_sn(hdr) + 1); or: ratp_set_an(!ratp_sn(hdr)); We define a pair of new ratp_set_next_sn() and ratp_set_next_an() macros that make it clear that the next value is desired, and also hide the computation of the actual flag value within the macro, so the previous example would now look like: ratp_set_next_an(ratp_sn(hdr)); Signed-off-by: Aleksander Morgado <aleksander@aleksander.es> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ratp: don't ignore data that may arrive in behaviour H1Aleksander Morgado2017-06-231-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an input packet arrives H1 that has data in it, we need to: * track sn_received * if we have data pending, send it * if we don't have data pending, send a plain ACK This process, as noted in RFC916, is the same as the I1 procedure, so go and run it: Go to the ESTABLISHED state and execute procedure I1 to process any data which might be in this packet. This fix allows the peer to queue data in the last packet doing the connection establishment. It doesn't apply to the barebox<->bbremote interaction because bbremote won't queue data until the connection is completely established, but it allows third party ratp implementations to do that.
