* lib: add weak clz/ctz functionsLucas Stach2018-02-211-0/+1
| | | | | | | | | | | | This is a copy of the Linux kernel implementation. This adds weak functions for the clz and ctz gcc builtins. Normally GCC will map those builtins to CPU instructions directly, but for CPUs where those are unavailable, we need to provide a fallback implementation. Fixes build of the zlib decompressor on ARMv4 CPUs. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * Add Reliable Asynchronous Transfer ProtocolSascha Hauer2016-01-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for Reliable Asynchronous Transfer Protocol (RATP) as described in RFC916. Communication over RS232 is often unreliable as characters are lost or misinterpreted. This protocol allows for a reliable packet based communication over serial lines. The implementation simply follows the state machine described in the RFC text with one exception. RFC916 uses a plain checksum for the transferred data. We decided to use CRC16 for greater robustness. Since this is the only RFC916 implementation we currently know of interoperability with other implementations should not matter.

* Add PBL console supportSascha Hauer2015-01-051-0/+2
| | | | | | | | | | | This adds simple console support to the PBL which makes it possible to print more complex messages in the PBL than just strings or hex numbers. For now puts_ll is used to print the messages, so it depends on CONFIG_DEBUG_LL which makes it more a debugging option. However, this could be extended later to get regular output from the PBL if desired. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM: MXS: introduce stmp device supportSascha Hauer2013-07-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | MXS specific devices have some common infrastructure in the kernel known as STMP devices. We have the same in barebox, but with a mxs_ prefix instead of a stmp_ prefix. As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.

* commands: change Y-Modem implementationRobert Jarzmik2012-11-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current Y-Modem implementation has some limitations: - Y-Modem/G protocol is not supported - Multiple files (aka. batch) transfers are not supported - Transfer speed over fast lines (USB console) is slow - Code is not trivial to maintain (personnal opinion) This implementation tries to address all these points by introducing loady2 command. The effects are : - transfer speed for Y-Modem over USB jumps from 2kBytes/s to 180kBytes/s - transfer speed for Y-Modem/G jumps to 200kBytes/s - multiple file transfers are possible This command was tested on a USB console and UART 9600bps serial line : - NAKs (and retransmissions) were tested for faulty serial lines - multiple file transfers were tested - Y-Modem, Y-Modem/G and X-Modem transfers were tested Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Tested-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
