* sunxi: usb: Drop AXP-sepcific VBUS detection and drive logicPaul Kocialkowski2015-04-15-50/+23
| | | | | | | | | VBUS detection and enable is now be used with virtual AXP GPIOs, so all the USB code has to use GPIO in every case and let sunxi_gpio do the heavy lifting.

* | ARM: fix arch/arm/Makefile for TegraMasahiro Yamada2015-04-11-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 79d75d752717 (ARM: move -march=* and -mtune= options to arch/arm/Makefile), all the Tegra boards are broken because the SPL is built for ARMv7. Insert Tegra-specific code to arch/arm/Makefile to set compiler flags for an earlier ARM architecture. Note: The v1 patch for commit 79d75d752717 *was* correct when it was submitted. Notice it was originally written for multi .config configuration where Kconfig set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for Tegra U-Boot Main/SPL, respectively. But, until it was merged into the mainline, commit e02ee2548afe (kconfig: switch to single .config configuration) had been already applied there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is important to have entry point in the beginning of .text section because it allows simple loading and execution of U-Boot. For example pre-bootloader loads U-Boot in memory starting from offset 0x81000000 and then just jumps to the same address. Otherwise pre-bootloader would need to find-out where entry-point is. In its turn if it deals with binary image of U-Boot there's no way for pre-bootloader to get required value. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There're 2 versions of motherboards that could be used in ARC SDP. The only important difference for U-Boot is different NAND IC in use: [1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP while [2] v3 board sports MT29F4G16ABADAWP They are almost the same except data bus width 8-bit in [1] and 16-bit in [2]. And for proper support of 16-bit data bus we have to pass NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing board type we're running on.

Version one of the footer is indicated by the magic number 0xA0FFFF9F at 12 bytes before the end of the flash block and version two is indicated by the magic number 0x464F4F54 0x464C5348 (ASCII for "FLSHFOOT") in the very last 8 bytes of the erase block. This command driver implements support for both versions of the AFS images (the name comes from the Linux driver in drivers/mtd/afs.c) and makes it possible to list images and load an image by name into the memory with these commands: afs - lists flash contents afs load <image> - loads image to address indicated in the image afs load <image> <addres> - loads image to a specified address This image scheme is used on the ARM Integrator family, ARM Versatile family, ARM RealView family (not yet supported in U-Boot) and ARM Versatile Express family up to and including the new Juno board for 64 bit development.

By collecting such options into the single place arch/arm/Makefile we can tell which options are missing at a glance. [3] Prepare for deprecating arch/*/cpu/*/config.mk Note: This commit just moves the compiler options so as not to change the behavior at all. It does not care about the correctness of the given options. Fox example, "-march=armv5te" might be better than "-march=armv4" for ARM946EJS, but it is beyond the scope this commit. Also, filling the missing -march=* and -tune=* is left to follow-up patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In stead of user_buffer_size, transfer_size should be used to pass to ahci_device_data_io(). transfer_size is the length that we want the low level function to transfer each time. If we use user_buffer_size which is the totally data length as parameter, low level function will actually create many SGs to transfer as many data as possible each time. That will produce many redundant data transfer. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* | | env_sf: Fix recovery defaultMario Schuknecht2015-04-07-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The u-boot environment is redundantly stored in a NOR flash on our boards. Redundant means that there are two places to store the environment. But only one of the two is active. I discovered that on one board the u-boot (env_sf) uses the environment from the second place and the Kernel (fw_printenv) uses the environment from the first place. To decide which is the active environment there is a byte inside the environment. 1 means active and 0 means obsolete. But on that board both environments had have a 1. This can happen if a power loss or reset occurs during writing the environment. In this situation the u-boot (env_sf) implementation uses the second environment as default. But the Kernel (fw_printenv) implementation uses the first environment as default. This commit corrects the default in the u-boot env_sf implementation when a problem was detected. Now the recovery default is the same like in all other environment implementations. E.g. fw_printenv and env_flash. This ensures that u-boot and Kernel use the same environment.
