Svyatoslav Ryhel 86e581a560 board: htc: endeavoru: add an early SPL RCM hook ... Unlike all other supported Tegra devices and most known Tegra devices, the HTC One X has no hardware way to enter APX/RCM mode, which may lead to a dangerous situation when, if BCT is set correctly and the bootloader is faulty, the device will hang in a permanent brick state. Exiting from this state can be done only by disassembling the device and shortening the testpad to the ground. To prevent this or to minimize the probability of such an accident, it was proposed to add the RCM rebooting hook as early into SPL as possible since SPL is much more robust and has minimal changes that can break bootflow. gpio_early_init_uart() function was chosen as it is the earliest function exposed for setup by the device. Hook performs a check for volume up button state and triggers RCM if it is pressed. Signed-off-by: Svyatoslav Ryhel <clamor95@gmail.com>		2024-01-05 18:05:42 +02:00
