* buildman: Refactor output optionsSimon Glass2014-08-13-26/+34
| | | | | | | | | We need the output options to be available in several places. It's a pain to pass them into each function. Make them properties of the builder and add a single function to set them up. At the same time, add a function which produces summary output using these options.

| | | | | | | | | | | | Originally buildman had some support for building the current source tree.

| | | | | | | | | | | | | | | | | | | | | | | | Instead of waiting for DC triple buffer to be cleared, this patch changes to wait for a relevant DP sync flow end interrupt to come when disabling sync BG flows.

* | lib: lmb: fix overflow in __lmb_alloc_base w/ large RAMStephen Warren2014-08-09-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a 32-bit system has 2GB of RAM, and the base address of that RAM is 2GB, then start+size will overflow a 32-bit value (to a value of 0). __lmb_alloc_base is affected by this; it calculates the minimum of (start+size of RAM) and max_addr. However, when start+size is 0, it is always less than max_addr, which causes the value of max_addr not to be taken into account when restricting the allocation's location. Fix this by calculating start+size separately, and if that calculation underflows, using -1 (interpreted as the max unsigned value) as the value instead, and then taking the min of that and max_addr. Now that start+size doesn't overflow, it's typically large, and max_addr dominates the min() call, and is taken into account. The user-visible symptom of this bug is that CONFIG_BOOTMAP_SZ is ignored on Tegra124 systems with 2GB of RAM, which in turn causes the DT to be relocated at the very end of RAM, which the ARM Linux kernel doesn't map during early boot, and which causes boot failures. With this fix, CONFIG_BOOTMAP_SZ correctly restricts the relocated DT to a much lower address, and everything works. Signed-off-by: Stephen Warren <swarren@nvidia.com>

Distros that install such a boot config file/script in those standard locations will get easy-to-set-up booting on HW that enables this generic $bootcmd. Boards can define the set of devices from which boot is attempted, and the order in which they are attempted. Users may later customize this set/order by edting $boot_targets. Users may interrupt the boot process and boot from a specific device simply by executing e.g.: $ run bootcmd_mmc1 or: $ run bootcmd_pxe This patch was originally written by Dennis Gilmore based on Tegra and rpi_b boot scripts. I have made the following modifications since then: * Boards must define the BOOT_TARGET_DEVICES macro in order to specify the set of devices (and order) from which to attempt boot. If needed, we can define a default directly in config_distro_bootcmd.h. * Removed $env_import and related variables; nothing used them, and I think it's better for boards to pre-load an environment customization file using CONFIG_PREBOOT if they need. * Renamed a bunch of variables to suit my whims:-) Signed-off-by: Dennis Gilmore <dennis@ausil.us> Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Marek Vasut <marex@denx.de> Acked-by: Simon Glass <sjg@chromium.org>

* | net: BOOTP retry timeout improvementsStephen Warren2014-08-09-11/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the BOOTP code sends out its initial request as soon as the Ethernet driver indicates "link up". If this packet is lost or not replied to for some reason, the code waits for a 1s timeout before retrying. For some reason, such early packets are often lost on my system, so this causes an annoying delay. To optimize this, modify the BOOTP code to have very short timeouts for the first packet transmitted, but gradually increase the timeout each time a timeout occurs. This way, if the first packet is lost, the second packet is transmitted quite quickly and hence the overall delay is low. However, if there's still no response, we don't keep spewing out packets at an insane speed. It's arguably more correct to try and find out why the first packet is lost. However, it seems to disappear inside my Ethenet chip; the TX chip indicates no error during TX (not that it has much in the way of reporting...), yet wireshark on the RX side doesn't see any packet. FWIW, I'm using an ASIX USB Ethernet adapter. Perhaps "link up" is reported too early or based on the wrong condition in HW, and we should add some fixed extra delay into the driver. However, this would slow down every link up event even if it ends up not being needed in some cases. Having BOOTP retry quickly applies the fix/WAR to every possible Ethernet device, and is quite simple to implement, so seems a better solution.

If the boot operation is aborted, this global state is not cleared. If "dhcp" is executed later without any arguments, BootFile is not cleared, and when the DHCP response is received, BootpCopyNetParams() writes the value into environment variable bootfile. This causes the following scenario: * Boot script executes dhcp; pxe get; pxe boot * User CTRL-C's the PXE menu, which causes the first menu item to be booted, which causes some file to be downloaded. (This boot-on-CTRL-C behaviour is arguably a bug too, but it's a separate bug and the bug this patch fixes would still exist if the user simply waited to press CTRL-C until "pxe boot" started downloading files) * User CTRL-C's the file downloads, but the filename is still written to the bootfile environment variable. * User re-runs the boot command, which in my case executes "dhcp; pxe get; pxe boot" again, and "dhcp" picks up the saved bootfile environment variable and proceeds to download a file that it shouldn't. To solve this, modify the implementation of "pxe get" to clear BootFile if the whole boot operation fails, which avoids this whole mess. An alternative would be to modify netboot_common() such that the no- arguments case explicitly clears the global variable BootFile. However, that would prevent the following command sequences from working: $ dhcp filename # downloads "filename" $ dhcp # downloads $bootfile, i.e. "filename" or: $ setenv bootfile filename $ dhcp # downloads $bootfile, i.e. "filename" ... and I assume someone relies on U-Boot working that way.
