      driver/ddr: Restruct driver to allow standalone memory space · 1d71efbb
      York Sun authored
      U-boot has been initializing DDR for the main memory. The presumption
      is the memory stays as a big continuous block, either linear or
      interleaved. This change is to support putting some DDR controllers
      to separated space without counting into main memory. The standalone
      memory controller could use different number of DIMM slots.

      cmd_bootm.c: Add 'booti' for ARM64 Linux kernel Images · d2b2ffe3
      Tom Rini authored
      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.

      net: More BOOTP retry timeout improvements · 92ac8acc
      Thierry Reding authored
      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 f59be6e8 ("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-relocation · d59476b6
      Simon Glass authored
      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.

      Add an I/O tracing feature · aa53233a
      Simon Glass authored
      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.

      usb: hub: remove CONFIG_USB_HUB_MIN_POWER_ON_DELAY · 77b83e6d
      Stephen Warren authored
      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.

      usb/gadget: add the fastboot gadget · 3aab70af
      Sebastian Siewior authored
      This patch contains an implementation of the fastboot protocol on the
      device side and documentation. This is based on USB download gadget
      infrastructure. The fastboot function implements the getvar, reboot,
      download and reboot commands. What is missing is the flash handling i.e.
      writting the image to media.
      
      v3 (Rob Herring):
      This is based on http://patchwork.ozlabs.org/patch/126798/ with the
      following changes:
      - Rebase to current mainline and updates for current gadget API
      - Use SPDX identifiers for licenses
      - Traced the history and added missing copyright to cmd_fastboot.c
      - Use load_addr/load_size for transfer buffer
      - Allow vendor strings to be optional
      - Set vendor/product ID from config defines
      - Allow Ctrl-C to exit fastboot mode
      v4:
      - Major re-write to use the USB download gadget. Consolidated function
      code to a single file.
      - Moved globals into single struct.
      - Use puts and putc as appropriate.
      - Added CONFIG_USB_FASTBOOT_BUF_ADDR and CONFIG_USB_FASTBOOT_BUF_SIZE to
      set the fastboot transfer buffer.
      v5:
      - Add CONFIG option documentation to README
      - Rebase using new downloader registration

      usb: dfu: fix boards wo USB cable detection · 75504e95
      Mateusz Zalega authored
      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.
