2018-04-07Add support for BeagleBoard.org PocketBeagleJason Kridner4-5/+17
Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x 55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more. https://beagleboard.org/pocket This was tested using the am335x_evm_usbspl_defconfig. Note that MII pins are enabled despite not having Ethernet on this board. This avoids an issue where otherwise many timeout errors would be generated. See https://e2e.ti.com/support/arm/sitara_arm/f/791/t/298976 for some related discussion.

2018-04-06board: MCR3000: Use smaller flash sector for environmentChristophe Leroy2-6/+6
Latest versions of u-boot have increased in size and require more than the 256kb allocated to it. The MCR3000 board is equipped with an AM29LV160DB boot flash which is organised as follows: - One 16kb block - Two 8kb block - One 32kb block - Thirty one 64kb blocks At the time being, u-boot is a single piece occupying the 256 first kbytes, then the environment is stored in the following 64kb block The environment being quite tiny, we save one 64kb block by embedding the environment in the first 8kb block, hence allowing to increase the monitor size to 320kb. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
2018-04-06common: env_embedded: allow fine placement of environment objectChristophe Leroy2-5/+5
Commit 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") dropped the .ppcenv section which was used in linking scripts to allow fine placement of embedded environment sections. This implies that GCC randomly places objects from env/embedded.o and environment is not guaranteed to be located at the correct address: 04003df8 g F .text 00000038 mii_init 04004000 g O .text 00000004 env_size 04004004 g O .text 00002000 environment 04006004 g F .text 00000040 .hidden __lshrdi3 This patch restores this capability by allocating each object marked with __UBOOT_ENV_SECTION__ into a different section. Hence 'environment' will be alone in .text.environment, allowing a fine placement in u-boot.lds with: . = DEFINED(env_offset) ? env_offset : .; env/embedded.o (.text.environment) Fixes: 7653942b10e9e ("common/env_embedded.c: drop support for CONFIG_SYS_USE_PPCENV") Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

Some config is redundant with Kconfig. Fix it. Also remove unused configs Move SDRAM_MAX_SIZE in the only place it is used include/environment.h already defines CONFIG_ENV_SIZE from CONFIG_ENV_SECT_SIZE and defines CONFIG_ENV_ADDR as (CONFIG_SYS_FLASH_BASE + CONFIG_ENV_OFFSET) remove BOOTARGS as bootargs is set by the different boot commands Fix CONFIG_SYS_INIT_RAM_ADDR and CONFIG_SYS_INIT_RAM_SIZE to be in line with CPM DPRAM organisation Remove CONFIG_SYS_GBL_DATA_SIZE, CONFIG_SYS_GBL_DATA_OFFSET and CONFIG_SYS_INIT_SP_OFFSET which are unused Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

2018-04-06powerpc: mpc8xx: initialisation of initial RAMChristophe Leroy1-7/+20
u-boot requires some RAM at startup, to store global data structure. RAM is also needed when we migrate to DM for some initial malloc This patch implements the proper init of that RAM by calling board_init_f_alloc_reserve() and board_init_f_init_reserve() Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>

In raspberrypi-firmware 7fdcd00e00a42a1c91e8bd6f5eb8352fe9358557 and later start.elf now sets the EMMC clock to 200 MHz.
