2018-12-10ti: remove usage of DM_I2C_COMPAT and don't disable DM_I2C in SPLJean-Jacques Hiblot
DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C API when DM_I2C is used. The goal is to eventually remove DM_I2C_COMPAT when all I2C "clients" have been migrated to use the DM API. This a step in that direction for the TI based platforms.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-07-26arm: mach-keystone: Fixes issue with return values in inline assemblySrinivas, Madan
The inline assembly functions in mon.c assume that the caller will check for the return value in r0 according to regular ARM calling conventions. However, this assumption breaks down if the compiler inlines the functions. The caller is then under no obligation to use r0 for the result. To fix this disconnect, we must explicitly move the return value from the smc/bl call to the variable that the function returns.

2017-07-26arm: mach-keystone: Updates mon_install for K2G HSMadan Srinivas
On early K2 devices (eg. K2HK) the secure ROM code does not support loading secure code to firewall protected memory, before decrypting, authenticating and executing it. To load the boot monitor on these devices, it is necessary to first authenticate and run a copy loop from non-secure memory that copies the boot monitor behind firewall protected memory, before decrypting and executing it. On K2G, the secure ROM does not allow secure code executing from unprotected memory. Further, ROM first copies the signed and encrypted image into firewall protected memory, then decrypts, authenticates and executes it. As a result of this, we cannot use the copy loop for K2G. The mon_install has to be modified to pass the address the signed and encrypted secure boot monitor image to the authentication API. For backward compatibility with other K2 devices and K2G GP, the mon_install API still supports a single argument. In this case the second argument is set to 0 by u-boot and is ignored by ROM Signed-off-by: Thanh Tran <thanh-tran@ti.com> Signed-off-by: Madan Srinivas <madans@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
