The mbedtls/* definition in file .mbedignore causes a compile error

[ccchang12]

I compile BLE_BatteryLevel example for target NUMAKER_PFM_NUC472 but get a error.

The root cause is the NUC472 supports H/W SHA and need to include mbedtls header. Due to the mbedtls/* definition in file .mbedignore, the H/W SHA code cannot find the header and encounters an error. Please remove the mbedtls/* definition to fix this issue.

Below is the compile error message.

@pan- @paul-szczepanek-arm I referenced this in mbed OS issue, this got our attention this week as these examples cant be build if a component or target (as reported above) includes mbedtls that is part of mbed OS.

I can't find the reason in the git log (almost no commit message ).

@0xc0170 The .mbedignore file is present for historical reasons, we can remove it. However it doesn't sounds healthy that the target HAL depends on a feature.

The latest master - nuvoton have crypto in mbedtls folder, not as previously was in target (see https://github.com/ARMmbed/mbed-os/tree/master/targets/TARGET_NUVOTON/TARGET_NUC472).

The .mbedignore file is present for historical reasons, we can remove it.

This should fix this issue! Thanks

Closing this issue as this would have been resolved in mbed OS 5.8.
