Define virtual timer resources for a platform to be able to control virtual timers, even if TF-A does not enable them. This is required for example when the secure world wants to reset the system. Virtual timers enabled from non-secure world can jeopardize the reset sequence due to pending interrupts. Change-Id: Ieb0ce4819809ae9c4ab11f9244a6cacf9437d6b4 Signed-off-by:

This framework only manages enabling and disabling regulators. Peripheral drivers have to register their regulator with stm32mp_regulator_register function, which calls plat_get_regulator. This function has to be defined at platform level, to bind the regulator ops depending on the regulator ID. The functions stm32mp_regulator_enable and stm32mp_regulator_disable can then be called inside drivers to manage their regulators. Change-Id: I981bc6083015b0e1c307a5a9559573b80f81fc69 Signed-off-by:

For SD-cards, CMD6 is used to switch functions, like setting high speed mode. As it has another meaning for eMMC, and may not work on standard capacity SD-cards, it must be checked with MMC_IS_SD_HC flag. As ACMD6 is also used, and will have the same index, a check on CMD/ACMD commands is done: a boolean is stored depending on previous command. It is set to true if CMD55 is issued, for other commands it is set to false. Change-Id: I6c2b9c7637656f858601ec075de1cb5f57af271a Signed-off-by:

On SD-cards, Switch Function Command (CMD6) is used to switch functions, like setting High Speed mode. It is useful for high capacity cards to double frequency (from 25MHz by default to 50MHz). If the SD-card is High Capacity, a CMD6 is issued after filling the device information. If High Speed mode is supported and the switch is OK, then the max_bus_freq can be set to 50MHz. The driver set_ios function should then be called to update peripheral configuration, especially clock prescaler. Change-Id: I2d6807aa7f9440d2b2f907a747cd3b47a2ba1545 Signed-off-by:

Add parameters to fill header version: Two new options are added (m and n) to fill header version major and minor. The default is v1.0 (major = 1, minor = 0) Fix image header on big endian hosts: Three header fields are not properly converted to little endian before assignment, resulting in incorrect header while executing stm32image on big endian hosts. Convert the value of the header fields version_number, image_checksum and edcsa_algorithm to little endian before the assignment. Don't force the base of strtol, since it's able to select the base automatically depending on the prefix of the value. This does not breaks the current build script that extracts the addresses, including the 0x prefix, from the map file. This change helps using stm32image in shell scripts where the addresses can be computed using the shell arithmetic expansion "$((...))", that produces a value in base decimal. The variable stm32image_header is declared with global visibility but is use in one function only, move it as local variable in the function. Fix error message on destination file: The error message on mmap() failure of destination file reports incorrectly information about the source file. Change the error message to match the file that causes the error. Change-Id: Iebc8c915297306845b3847b32f9516443a515c97 Signed-off-by:

The RELA_SECTION is redefined for AARCH32, as the created section is .rel.dyn and the symbols are .rel*. In BL32 linker script, .dynsym .dynstr .hash .gnu.hash are discarded. And no more used __BSS_SIZE__ and __COHERENT_RAM_UNALIGNED_SIZE__ symbols are removed. Change-Id: I92bafe70e6b77735f6f890f32f2b637b98cf01b9 Signed-off-by:
