* | hush: add CONFIG_HUSH_PARSER to KconfigMasahiro Yamada2014-11-23-12/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The README file states that the macros beginning with "CONFIG_SYS_" depend on the hardware etc. and should not be meddled with if you do not what you're doing. We have already screwed up with this policy; we have given the prefix "CONFIG_SYS_" to many user-selectable configurations. Here, "CONFIG_SYS_HUSH_PARSER" is one of them. Users can enable it if they want to use a more powerful command line parser, or disable it if they only need a simple one. This commit attempts to rename CONFIG_SYS_HUSH_PARSER to CONFIG_HUSH_PARSER and move it to Kconfig. Every board maintainer is expected to enable CONFIG_HUSH_PARSER (= add "CONFIG_HUSH_PARSER=y" to his defconfig file) and remove "#define CONFIG_SYS_HUSH_PARSER" from his header file.

One possible reason for the delay can be that the server checks (typically using an ARP request) that the IP it's about to hand out isn't in use yet. To make matters worse, some servers may also queue up requests and process them sequentially, which can cause excessively long delays if clients retry too fast. Commit f59be6e850b3 ("net: BOOTP retry timeout improvements") shortened the retry timeouts significantly, but the BOOTP/DHCP implementation in U-Boot doesn't handle that well because it will ignore incoming replies to earlier requests. In one particular setup this increases the time it takes to obtain a DHCP lease from 630 ms to 8313 ms. This commit attempts to fix this in two ways. First it increases the initial retry timeout from 10 ms to 250 ms to give DHCP servers some more time to respond. At the same time a cache of outstanding DHCP request IDs is kept so that the implementation will know to continue transactions even after a retransmission of the DISCOVER message. The maximum retry timeout is also increased from 1 second to 2 seconds. An ID cache of size 4 will keep DHCP requests around for 8 seconds (once the maximum retry timeout has been reached) before dropping them. This should give servers plenty of time to respond. If it ever turns out that this isn't enough, the size of the cache can easily be increased. With this commit the DHCP lease on the above-mentioned setup still takes longer (1230 ms) than originally, but that's an acceptable compromise to improve DHCP lease acquisition time for a broader range of setups. To make it easier to benchmark DHCP in the future, this commit also adds the time it took to obtain a lease to the final "DHCP client bound to address x.x.x.x" message.

* | Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+13
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are to have driver model before relocation we need to support some way of calling memory allocation routines. The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>

* Add an I/O tracing featureSimon Glass2014-06-20-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging drivers it is useful to see what I/O accesses were done and in what order. Even if the individual accesses are of little interest it can be useful to verify that the access pattern is consistent each time an operation is performed. In this case a checksum can be used to characterise the operation of a driver. The checksum can be compared across different runs of the operation to verify that the driver is working properly. In particular, when performing major refactoring of the driver, where the access pattern should not change, the checksum provides assurance that the refactoring work has not broken the driver. Add an I/O tracing feature and associated commands to provide this facility. It works by sneaking into the io.h heder for an architecture and redirecting I/O accesses through its tracing mechanism. For now no commands are provided to examine the trace buffer. The format is fairly simple, so 'md' is a reasonable substitute. Note: The checksum feature is only useful for I/O regions where the contents do not change outside of software control. Where this is not suitable you can fall back to manually comparing the addresses. It might be useful to enhance tracing to only checksum the accesses and not the data read/written.
