Do not set these options unless they apply! + - Tegra SoC options: + CONFIG_TEGRA_SUPPORT_NON_SECURE + + Support executing U-Boot in non-secure (NS) mode. Certain + impossible actions will be skipped if the CPU is in NS mode, + such as ARM architectural timer initialization. + + - Driver Model + Driver model is a new framework for devices in U-Boot + introduced in early 2014. U-Boot is being progressively + moved over to this. It offers a consistent device structure, + supports grouping devices into classes and has built-in + handling of platform data and device tree. + + To enable transition to driver model in a relatively + painful fashion, each subsystem can be independently + switched between the legacy/ad-hoc approach and the new + driver model using the options below. Also, many uclass + interfaces include compatibility features which may be + removed once the conversion of that subsystem is complete. + As a result, the API provided by the subsystem may in fact + not change with driver model. + + See doc/driver-model/README.txt for more information. + + CONFIG_DM + + Enable driver model. This brings in the core support, + including scanning of platform data on start-up. If + CONFIG_OF_CONTROL is enabled, the device tree will be + scanned also when available. + + CONFIG_CMD_DM + + Enable driver model test commands. These allow you to print + out the driver model tree and the uclasses. + + CONFIG_DM_DEMO + + Enable some demo devices and the 'demo' command. These are + really only useful for playing around while trying to + understand driver model in sandbox. + + CONFIG_SPL_DM + + Enable driver model in SPL. You will need to provide a + suitable malloc() implementation. If you are not using the + full malloc() enabled by CONFIG_SYS_SPL_MALLOC_START, + consider using CONFIG_SYS_MALLOC_SIMPLE. In that case you + must provide CONFIG_SYS_MALLOC_F_LEN to set the size. + In most cases driver model will only allocate a few uclasses + and devices in SPL, so 1KB should be enable. See + CONFIG_SYS_MALLOC_F_LEN for more details on how to enable + it. + + CONFIG_DM_SERIAL + + Enable driver model for serial. This replaces + drivers/serial/serial.c with the serial uclass, which + implements serial_putc() etc. The uclass interface is + defined in include/serial.h. + + CONFIG_DM_GPIO + + Enable driver model for GPIO access. The standard GPIO + interface (gpio_get_value(), etc.) is then implemented by + the GPIO uclass. Drivers provide methods to query the + particular GPIOs that they provide. The uclass interface + is defined in include/asm-generic/gpio.h. + + CONFIG_DM_SPI + + Enable driver model for SPI. The SPI slave interface + (spi_setup_slave(), spi_xfer(), etc.) is then implemented by + the SPI uclass. Drivers provide methods to access the SPI + buses that they control. The uclass interface is defined in + include/spi.h. The existing spi_slave structure is attached + as 'parent data' to every slave on each bus. Slaves + typically use driver-private data instead of extending the + spi_slave structure. + + CONFIG_DM_SPI_FLASH + + Enable driver model for SPI flash. This SPI flash interface + (spi_flash_probe(), spi_flash_write(), etc.) is then + implemented by the SPI flash uclass. There is one standard + SPI flash driver which knows how to probe most chips + supported by U-Boot. The uclass interface is defined in + include/spi_flash.h, but is currently fully compatible + with the old interface to avoid confusion and duplication + during the transition parent. SPI and SPI flash must be + enabled together (it is not possible to use driver model + for one and not the other). + + CONFIG_DM_CROS_EC + + Enable driver model for the Chrome OS EC interface. This + allows the cros_ec SPI driver to operate with CONFIG_DM_SPI + but otherwise makes few changes. Since cros_ec also supports + I2C and LPC (which don't support driver model yet), a full + conversion is not yet possible. + + + ** Code size options: The following options are enabled by + default except in SPL. Enable them explicitly to get these + features in SPL. + + CONFIG_DM_WARN + + Enable the dm_warn() function. This can use up quite a bit + of space for its strings. + + CONFIG_DM_STDIO + + Enable registering a serial device with the stdio library. + + CONFIG_DM_DEVICE_REMOVE + + Enable removing of devices. - - Linux Kernel Interface: CONFIG_CLOCKS_IN_MHZ diff --cc include/configs/ls2085a_common.h index 17a1cde039,01c85666dd..f80efedeb2 --- a/include/configs/ls2085a_common.h +++ b/include/configs/ls2085a_common.h @@@ -13,8 -13,11 +13,12 @@@ #define CONFIG_FSL_LSCH3 #define CONFIG_LS2085A #define CONFIG_GICV3 +#define CONFIG_FSL_TZPC_BP147 + /* Errata fixes */ + #define CONFIG_ARM_ERRATA_828024 + #define CONFIG_ARM_ERRATA_826974 + /* Link Definitions */ #define CONFIG_SYS_TEXT_BASE 0x30001000
