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>

|
|
* Motorola S-Record Format:
|
|
*
|
|
* Motorola S-Records are an industry-standard format for
|
|
* transmitting binary files to target systems and PROM
|
|
* programmers. LSI Logic have extended this standard to include
|
|
* an S4-record containing an address and a symbol.
|
|
*
|
|
* The extended S-record standard is as follows:
|
|
*
|
|
* S<type><length><address><data....><checksum>
|
|
* S4<length><address><name>,<checksum>
|
|
*
|
|
* Where:
|
|
*
|
|
* type
|
|
* is the record type. Where:
|
|
*
|
|
* 0 starting record (optional)
|
|
* 1 data record with 16-bit address
|
|
* 2 data record with 24-bit address
|
|
* 3 data record with 32-bit address
|
|
* 4 symbol record (LSI extension)
|
|
* 5 number of data records in preceding block
|
|
* 6 unused
|
|
* 7 ending record for S3 records
|
|
* 8 ending record for S2 records
|
|
* 9 ending record for S1 records
|
|
*
|
|
* length
|
|
* is two hex characters. This defines the length of the
|
|
* record in bytes (not characters). It includes the address
|
|
* field, the data field, and the checksum field.
|
|
*
|
|
* address
|
|
* is 4, 6, or 8 characters. Corresponding to a 16-, 24-, or
|
|
* 32-bit address. The address field for S4 records is
|
|
* always 32 bits.
|
|
*
|
|
* data
|
|
*
|
|
* Are the data bytes. Each pair of hex characters represent
|
|
* one byte in memory.
|
|
*
|
|
* name
|
|
* Is the symbol name. The symbol is terminated by a ','.
|
|
*
|
|
* checksum
|
|
* Is the one's complement of the 8-bit checksum.
|
|
*
|
|
* Example
|

*
|
|
* S0030000FC
|
|
* .

|
* .

|
|
* S70500000000FA
|
|
*
|
|
* The S0 record starts the file. The S3 records contain the
|
|
* data. The S7 record contains the entry address and terminates
|
|
* the download.
