2014-08-30cmd_bootm.c: Add 'booti' for ARM64 Linux kernel ImagesTom Rini
The default format for arm64 Linux kernels is the "Image" format, described in Documentation/arm64/booting.txt. This, along with an optional gzip compression on top is all that is generated by default. The Image format has a magic number within the header for verification, a text_offset where the Image must be run from, an image_size that includes the BSS and reserved fields. This does not support automatic detection of a gzip compressed image. Signed-off-by: Tom Rini <trini@ti.com>

2014-08-21net: More BOOTP retry timeout improvementsThierry Reding
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.

2014-07-23Add a simple malloc() implementation for pre-relocationSimon Glass
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>

MC firmware and DPL images are copied from their location in NOR flash to DDR. MC registers are updated with the location of these images. Deasserting the reset bit of MC GCR register releases core 0 to run. Core 1 will be released by MC firmware. Stop bits are not touched for this step. U-boot waits for MC until it boots up.

2014-06-20Add an I/O tracing featureSimon Glass
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.

2014-06-01usb: hub: remove CONFIG_USB_HUB_MIN_POWER_ON_DELAYStephen Warren
Now that we wait the correct specification-mandated time at the end of usb_hub_power_on(), I suspect that CONFIG_USB_HUB_MIN_POWER_ON_DELAY has no purpose. For cm_t35.h, we already wait longer than the original MIN_POWER_ON_DELAY, so this change is safe. For gw_ventana.h, we will wait as long as the original MIN_POWER_ON_DELAY iff pgood_delay was at least 200ms. I'm not sure if this is the case or not, hence I've CC'd relevant people to test this change.

2014-05-05usb: dfu: fix boards wo USB cable detectionMateusz Zalega
Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.
