| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Banana Pi is an A20 based development board using Raspberry Pi compatible IO headers. It comes with 1 GB RAM, 1 Gb ethernet, 2x USB host, sata, hdmi and stereo audio out + various expansion headers: http://www.lemaker.org/ Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done for sun7i only since I don't have access to any other sunxi platforms with sata included. The PHY setup is derived from the Alwinner releases and Linux, but is mostly undocumented. The Allwinner AHCI controller also requires some magic (and, again, undocumented) DMA initialisation when starting a port. This is added under a suitable ifdef. This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on contents of Linux DTS files, including SATA power pin config taken from the DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

This patch limits itself to the nios2 architecture. The problem is that for the size_t (%zu, %zd, ...) arguments of printf GCC does not verify the type match to size_t type. It verifies the type match to the compiler-defined __SIZE_TYPE__ type. Thus, if size_t is defined different from __SIZE_TYPE__ - warnings inevitably appear. There is a comment by Thomas Chou to the (rejected) patch: http://patchwork.ozlabs.org/patch/272102/ which explains that the older GCC toolchains (gcc-3.4.6 and gcc-4.1.2) expect size_t to be "unsigned long" and the newer expect it to be "unsigned int". Thus, no matter how we define size_t - either way warnings appear when using some GCC version. By rejecting that patch, a choice was made to prefer older GCC versions and leave the warnings when building with the newer toolchains. Personally, I disagree with this choice... In any case, this patch proposes a way to fix the warnings for any GCC version. Just define size_t using the __SIZE_TYPE__ compiler-defined type and the type verification will pass. I tested that this fixes the warning on GCC 4.8.3. I don't have an older toolchain to test with, but __SIZE_TYPE__ was definitely defined in GCC 3.4.6, so it should work there too.

It has been hard for Python 3 users because Python 2 and Python 3 are not compatible with each other. We are not happy about adding a new host tool dependency (in this case, Python version dependency) for the core build process. After some discussion, we decided to use only basic tools. The script may get a bit more unreadable by shell scripting, but we believe it is worthwhile. In addition, this commit revives "<board>_config" target that is equivalent to "<board>_defconfig" for backwards compatibility. It is annoying to adjust various projects which use U-Boot.

* | | | net: More BOOTP retry timeout improvementsThierry Reding2014-08-21-8/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's not unusual for DHCP servers to take a couple hundred milliseconds to respond to DHCP discover messages. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b3dd64f5d537 "bootm: use genimg_get_kernel_addr()" introduced a bug for booting FIT image. It's because calling fit_parse_config() twice will give us wrong value in img_addr. Add a new function genimg_get_kernel_addr_fit() whichl will always return fit_uname_config and fit_uname_kernel for CONFIG_FIT. genimg_get_kernel_addr() will ignore those to parameters.
