Except Linux no other component (i.e., u-boot, fsbl or BootRom) of the software stack supports software ecc engine. So, make hw-ecc as the default ecc mode.

The xhci host controller driver trying to queue the URB's and it is getting halted at the endpoint, thereby hitting the BUG_ON's. Mostly these kind of random issues are seen on faulty boards. Removing these BUG_ON's from the U-Boot xhci code, as in Linux kernel xhci code BUG_ON/BUG's are removed entirely. Please also note, that BUG_ON() is not recommended any more in the Linux kernel. Similar issue has been observed on TI AM437x board and they created a patch in Linux kernel as below https://patches.linaro.org/project/linux-usb/patch/[email protected]/ Signed-off-by: Venkatesh Yadav Abbarapu <[email protected]> State: pending

Based on DT binding dwc_usb3 is single entry without anything else. That's why combination dwc3_usb3, otg is not allowed.

When CONFIG_SYS_REDUNDAND_ENVIRONMENT is enabled, by default env is getting saved to redundant environment irrespective of primary env is present or not. It means even if primary and redundant environment are not present, by default, env is getting stored to redundant environment. Even if primary env is present, it is choosing to store in redudndant env. Ideally it should look for primary env and choose to store in primary env if it is present. If both primary and redundant env are not present then it should save in to primary env area. Fix the issue by making env_valid = ENV_INVALID when both the environments are not present.

SPL FIT load checks the signature on loadable images but just continues in the case of a failure. This is undesirable behavior because the boot process depends on the authenticity of each loadable part. Adding CONFIG_SPL_FIT_SIGNATURE_STRICT to halt the platform when any image fails its signature check, including loadable parts. SPL already supports image signature verification but had no mechanism to check that the FIT's configuration block was signed correctly. Add a check near the start of spl_load_simple_fit that verifies the FIT's configuration block, and fails if it's not present or the signature doesn't match what's stored in the SPL DTB.

… command
When running "i2c md 0 0 80000100", the function do_i2c_md parses the
length into an unsigned int variable named length. The value is then
moved to a signed variable:
int nbytes = length;
#define DISP_LINE_LEN 16
int linebytes = (nbytes > DISP_LINE_LEN) ? DISP_LINE_LEN : nbytes;
ret = dm_i2c_read(dev, addr, linebuf, linebytes);
On systems where integers are 32 bits wide, 0x80000100 is a negative
value to "nbytes > DISP_LINE_LEN" is false and linebytes gets assigned
0x80000100 instead of 16.
The consequence is that the function which reads from the i2c device
(dm_i2c_read or i2c_read) is called with a 16-byte stack buffer to fill
but with a size parameter which is too large. In some cases, this could
trigger a crash. But with some i2c drivers, such as drivers/i2c/nx_i2c.c
(used with "nexell,s5pxx18-i2c" bus), the size is actually truncated to
a 16-bit integer. This is because function i2c_transfer expects an
unsigned short length. In such a case, an attacker who can control the
response of an i2c device can overwrite the return address of a function
and execute arbitrary code through Return-Oriented Programming.
Fix this issue by using unsigned integers types in do_i2c_md. While at
it, make also alen unsigned, as signed sizes can cause vulnerabilities
when people forgot to check that they can be negative.
