It was revealed that when the fastboot_tx_write_str function is called without the previously initialized fastboot_func->in_req->complete field, a copy of in_req will be sent to the I/O requests queue without an initialized field. Moving a piece of code with the initializing of the fastboot_func->in_req->complete field above transmit_tx allows to solve this problem.

2020-09-01f_sdp: Change bInterval of interrupt endpoint to 3Sherry Sun1-2/+2
Since the USB HID limits the maximum bandwidth(3072) for interrupt endpoint transfers, when the bInterval set to 1, we can only support 3 boards to run sdp at the same time. In order to support more boards, change the bInterval of interrupt endpoint to 3, which will not affect the transmission speed.

EP0 has been used to transfer file data in sdp before, but the max packetsize of ep0 is 64 bytes. So in order to improve the file transfer speed, here add the EP1_OUT interrupt endpoint which max packetsize is set to 1024 byte. After testing, it turns out that using ep1out is twice as fast as using ep0 while receiving data in sdp.

2020-09-01f_sdp: Support searching and loading FIT or container imagePeng Fan1-12/+58
Add support to f_sdp to search and load iMX8 container image or iMX8M FIT image by new UUU command SDPV. When using the SDPV, the uuu will continue to send out data after first level boot loader used by ROM. This means uuu won't skip to the offset of the second boot loader, and the padding data before second boot loader will be sent out. So we have to search the FIT header or container header in the buffer that SDP received. Also change to more common method to exit f_sdp handler not depending on SPL_FIT_FOUND flag because container loader won't set this. Signed-off-by: Peng Fan <peng.fan@nxp.com>

2020-09-01fastboot: Add support for 'reboot fastboot' commandRoman Kovalivskyi1-0/+2
Android 10 adds support for dynamic partitions and in order to support this userspace fastboot must be used[1]. New tool fastbootd is included into recovery. Userspace fastboot works from recovery and is launched if: 1) - Dynamic partitioning is enabled 2) - Boot control block has 'boot-fastboot' value into command field The bootloader is expected to load and boot into the recovery image upon seeing boot-fastboot in the BCB command. Recovery then parses the BCB message and switches to fastbootd mode[2]. Please note that boot script is expected to handle 'boot-fastboot' command in BCB and load into recovery mode. Bootloader must support 'reboot fastboot' command which should reboot device into userspace fastboot to accomodate those changes[3]. Another command that bootloader must support[3] is 'reboot recovery'. This command should simply reboot device into recovery mode.

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada7-8/+8
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit.

But in some corner cases, it would switch to CD-ROM unexpected. This issue results in Lan Function Disabled. While USB PHY transits to P3 from P0 due to the absent of transmitter control, it would issues undefined signal to its link partner.

Enabling this Auto Retry feature in controller will make the core send a non-terminanting ACK upon such transaction errors. That is, ACK TP with Retry=1 and Nump != 0. Doing so will give controller a chance to recover from transient error conditions.
