Instead of stringizing the paths to binary files, add them as string
defines on the command line (e.g. -DFOO=\"BAR\" instead of -DFOO=BAR).
This prevents macros from being expanded inside the string value itself.
For example, -DFOO=/path/with-linux-in-it would have been expanded to
"/path/with-1-in-it" because `linux=1` is one of the standard GCC
defines.

Currently tb_fw_cfg_dtb size is fixed to max, which is generally a page
(but depend on the platform). Instead, read the actual size of the dtb
with the libfdt "fdt_totalsize" function.
This avoid flushing extra memory after updating the dtb with mbedtls
heap information when shared heap is used.

The current range check for the offset is wrong: it is counting bytes,
while indexing an array of uint32_t. Since the offset is always zero,
the parameter is unnecessary. Instead of adding more code to fix the

This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.

For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.

"Strict checking" is a mode where secure world can access
secure-only areas unlike legacy mode where secure world could
access non-secure spaces as well. Secure-only areas are defined
as the TZ-DRAM carveout and any GSC with the CPU_SECURE bit set.
This mode not only helps prevent issues with IO-Coherency but aids
with security as well.

This patch implements the programming sequence required to enable
strict checking mode for Tegra194 SoCs.

This patch adds support to save the system suspend entry and exit
markers to TZDRAM to help the trampoline code decide if the current
warmboot is actually an exit from System Suspend.

The Tegra194 platform handler sets the system suspend entry marker
before entering SC7 state and the trampoline flips the state back to
system resume, on exiting SC7.

This patch does the following:
- cstate_info variable is used to pass on requested cstate to mce
- Currently, cg_cstate is encoded using 2 bits(bits 8, 9) in cstate_info
- cg_cstate values can range from 0 to 7, with 7 representing cg7
- Thus, cg_cstate is to be encoded using 3 bits (val: 0-7)
- Fix this, as per ISS and ensure bits 8, 9, 10 are used
